stddef.h: No such file or directory

[Brian Cuthie]

I'm trying to build a 386 embedded development environment using the
cdk-src gnu distribution on ftp.cygnus.com hosted on a Pentium FreeBSD
2.2.5 box.  While attempting to "make all-gcc" the build fails with
"SYSCALLS.c:86 stddef.h: No such file or directory".  I'm building from
the src root, with "--target=i386-any-coff" (I think that's what I want
-- comments?).  

Before I spend a week recursing through the Makefiles, anyone know
off-hand what might be causing this (yes, I know the file's missing).
The stddef.h file is in "ginclude", which appears not to be included in
the xgcc invocation that fails.  I'm just not quite sure why and I don't
want to just move it to make things happy, without knowing the
ramifications of such a change.

Thanks.
