fix order of importing modules and resolving duplicates handlers
* module/ice-9/boot-9.scm (define-module*): Resolve duplicates handlers
only after importing modules. Fixes a bug in which a module with
#:use-module (oop goops) but whose merge-generics handler got resolved
to noop instead of the real merge-generics handler. I can't think of
an easy way to test this, though.
Thanks to David Pirotte for the report!

fix a couple of leaks
* libguile/bytevectors.h:
* libguile/bytevectors.c (scm_c_take_gc_bytevector): Rename this
internal function, from scm_c_take_bytevector. This indicates that
unlike the other scm_take_* functions, this one takes GC-managed
memory.
* libguile/objcodes.c (scm_objcode_to_bytecode):
* libguile/vm.c (really_make_boot_program): Use
scm_gc_malloc_pointerless, not scm_malloc. Thanks to Stefan
Israelsson Tampe!
* libguile/r6rs-ports.c:
* libguile/strings.c: Adapt to renames.

reword open-file docs

-writes all bytes unchanged. On Unix-like systems there is no such
-distinction, text files already contain just newlines and no
-conversion is ever made. The @code{b} flag is accepted on all

address@hidden here just adds @code{O_BINARY} to the underlying @code{open}

+To provide this property, the file will be opened with the 8-bit

+
+This option had another historical meaning, for DOS compatibility: in
+the default (textual) mode, DOS reads a CR-LF sequence as one LF byte.
+The @code{b} flag prevents this from happening, adding @code{O_BINARY}
+to the underlying @code{open} call. Still, the flag is generally useful
+because of its port encoding ramifications.

In theory we could create read/write ports which were buffered
in one direction only. However this isn't included in the
