Well, I was "helping" the makefiles a bit by setting some extra include
paths.  This is necessitated by the peculiar environment I have to use here --
most of the extra software on our site is modularized, with each package in a
separate directory, and *not* located in /usr/local, /usr/lib, etc.
Unfortunately the configure scripts do not at present allow for --with-*-path=
for each required package, so I have had to fiddle quite a bit with gcc
environment variables and makefile variables to get all the -I, -L and -R
paths set up.

Thanks -- what did work was that I needed to remove
$GNUSTEP_ROOT/{Local,Network,System} and then do a complete reinstall of
core/make and then rebuild core/base.  Because this is solaris, of course, I
can't just get it to install using gcc -- I occasionally have to switch from
straight gcc to gcc configured with --native so the links won't segfault.
Fortunately we have both versions installed and I can switch between them when
necessary.
