+From Gerald Pfeifer: The last couple of months have seen several GCC
+(GNU Compiler Collection) releases, first GCC 4.4.5 in October, then
+GCC 4.5.2 in December and we are working full steam to brush up the
+first release in the 4.6 series
+GCC 4.6 will bring support for the Xilinx MicroBlaze softcore
+processor on the backend and a new frontend (and run-time library) for
+the Go language, plus many new Objective-C features, such as declared
+and synthesized properties, dot syntax, fast enumeration, optional
+protocol methods, method/protocol/class attributes, class extensions,
+and a new GNU Objective-C runtime API.
+GCC 4.6 is also adding a new optimization level @code{-Ofast} that is
address@hidden with options that can affect standards compliance but
+result in better optimized code.  The link-time optimizations (LTO) we
+introduced with GCC 4.5 have been improved, stabilized and reduced in
+terms of resource consumption which allows GCC to build itself or
+Mozilla Firefox with LTO.  As a user you can control how many
+compilations to execute via -flto=N.  Inlining heuristics and
+interprocedural optimizations have been tuned heavily, too.
+Back to frontends, stack checking for Ada has been tightened and now
+detects all overflows on several platforms; experimental support for
+the upcoming C1X standard has been added, new function attributes
address@hidden and @code{callee_pop_aggregate}, and a new warning
address@hidden  Support for the upcoming C++0x standard has
+seen a lot of love and care and C++ code generation can be tuned more
+finely (cf.@: new options @code{-fstrict-enums} and
+On systems supporting the new libquadmath library, GNU Fortran now
+also supports a quad-precision, @code{kind=16} floating-point data
+type (@code{REAL(16)}, @code{COMPLEX(16)}).  The @code{-fwhole-file}
+command-line option is now enabled by default which improves code
+generation and diagnostics, and both Fortran 2003 and Fortran 2008
+support have seen their fair dose of enhancements.
+In terms of platform enhancements, @code{-march=core2} (and
address@hidden) provides support for Intel address@hidden,
address@hidden for Intel i3/i5/i7 and @code{-march=btver1} gives
+you support for AMD Bobcat (family 14).  Darwin, FreeBSD, MinGW and
+Cygwin now all support @code{__float128} on 32-bit x86 targets.  MIPS
+now supports the Loongson 3A processor and s390x added full support
+for the zEnterprise z196 processor with a number of new instructions
+As far as operating systems go, GCC provides a convenient way of
+building native libraries and applications for the Android platform
+and on Windows @code{#pragma push_macro} & @code{#pragma pop_macro},
+decimal floating point and more have been added.
+Should you find any issue testing this forthcoming release, or any
+other, please make use of our updated Bugzilla at

-From Thomas Schwinge: Yeah, that's right!  The GNU Hurd is the GNU

-most active project either, but a handful of volunteers (a small
-handful, mostly) are still plowing their way through the terrain of a
-steadily changing (and improving) Free Software world, striving to

address@hidden We had Zheng Da work on user-space device drivers, based on L4's

-completion.  But due to modern revision control systems, all his

+Originally started as the GNU project's take at replacing proprietary

+According to our mission statement, the goal is creating @emph{a

+operating system research to the mainstream.  More concretely, it's a

+The Hurd doesn't fully deliver on the @emph{everyday usability} goal

+Apart from having done a lot of other work, Samuel Thibault, our Jack
+of all trades, merged his development branch that added Xen domU
+support to GNU Mach, which makes it possible to run a GNU/Hurd system
+as a Xen guest.  Development of this started in 2007, and since then
+it has been heavily tested by using it for the Debian GNU/Hurd build
+servers, most of our public GNU/Hurd systems,
address@hidden://}, and the
+Hurd project's wiki web server.
+We had Zheng Da work on a new hardware device driver framework, which
+is based on the Dresden L4 (Fiasco) group's DDE project, and allows
+running modern Linux kernel drivers as user-space server processes.
+Many network cards already work perfectly with this new framework.
+(It has not yet been integrated into the mainstream Hurd code base, so
+it needs to be compiled and set up by hand.)  Other driver classes,
+such as hard disk controllers, will require further work.
+As in the previous years, we again participated in the Google Summer
+of Code 2010.  Olaf Buddenhagen is our main guy for organizing this.
+J@'er@'emie Koenig ported the modern Debian Installer to Debian
+GNU/Hurd.  Installation images using the new installer are replacing
+the previous CD images, which were using an installer based on the old
+Debian boot floppies (and running under the Linux kernel)---Philip
+Charles has been maintaining these single-handedly for almost ten
+years!  The new installer images are available from
+Emilio Pozuelo Monfort was investigating specific compatibility
+problems exposed by the extensive test suites coming with some
+software packages.  Emilio's analysis uncovered a number of
+programming errors in the Hurd code, and he fixed several of them.  As
+these typically affected other programs too, this improved stability
+and compatibility in general.
+J@'er@'emie Koenig created a new implementation of a @command{procfs}
+translator, which is considerably more robust and efficient than the
+previous one.  Tools such as @command{top} can now be used without
+Some other translators (@command{gopherfs}, @command{netio},
address@hidden) which have been created by external contributors in
+the past have been fixed up by Manuel Menal, and packaged in Debian.
+Thus, some of the results of Hurd's extensible architecture are now
+easier to access, and these updated translators can serve as examples
+for other developers to implement their own ideas.
+In addition to various general stability, compatibility, and
+portability fixes, several people (Samuel Thibault, Pino Toscano,
+Emilio Pozuelo Monfort, and others) have been working on fixing issues
+with specific Debian packages.  So far, about 68% of all Debian
+packages are also available for Debian GNU/Hurd.
+Michael Walker started the Arch Hurd distribution, and together with
+other enthusiastic Arch developers (Allan McRae, Matthias Lanzinger,
+Alexander Preisinger, Stephen Gilles, Diego Nieto Cid) they got it
+working in an amazingly short amount of time, both as an installable
+system, and a live CD.  So now there is a choice between two
+well-featured distributions for the Hurd.  These new people of course
+also help forwarding Hurd development in general---Diego in particular
+contributed various patches to the Hurd console and other components.
+Carl Fredrik Hammar finished and presented his thesis, ``Generalizing
+mobility for the Hurd'',
 and passed with distinction.
