cygwin build problems on gcc-3_0-branch and main-trunk

["Immanuel, Gidado-Yisa" <avm3 at cdc dot gov>]

I want to investigate the problem, but I need a little assistance
at this point.  I've tried both the main-trunk, and the
gcc-3.0-branch. I've also tried configuring for just 'c++' as well
as 'c++,java' (hence my posting to gcc@gcc.gnu.org; I'm not on
gcc@gcc, so please reply to me directly).

In all 4 cases I get a similar variation on the errors posted
below during 'make bootstrap'.
 
PLATFORM: Windows2000, cygwin: 1.1.8-2, 933Mhz

GCC:  Reading specs from /usr/lib/gcc-lib/i686-pc-cygwin/2.95.3-2/specs
      gcc version 2.95.3-2 (cygwin special)

CONFIGURATION: gcc-3_0-branch (same thing happens for 'c++,java')
  ../gcc/configure --with-gcc-version-trigger=/d/dev/gnu2/gcc/gcc/version.c
  --host=i686-pc-cygwin --enable-threads=posix --prefix=/d/dev/gcc
  --enable-shared --enable-languages=c++ --disable-win32-registry
  --norecursion
