mingw svn trunk failure

[Bob Rossi <bob_rossi at cox dot net>]

Hi,

Is this the correct place to talk about problems compiling gcc on mingw?

If I checkout svn trunk, and do, 

mkdir gcc-builddir-1
cd gcc-builddir-1
../gcc/configure  --disable-werror  --with-gmp=/home/bobbybrasko/gcc/gmp/gmp \
--with-mpfr=/home/bobbybrasko/gcc/mpfr/prefixdir  --host=mingw32 \
--target=mingw32 --prefix=/c/mingw  --program-suffix="-4.1"  --with-gcc \
--with-gnu-ld  --with-gnu-as  --enable-threads=win32  --disable-nls \
--enable-languages=c,c++  --disable-win32-registry  --disable-shared \
--enable-static  --without-x  --enable-libstdcxx-debug \
2>&1 | tee configure-out.txt

then I do,

cd gcc-builddir-1
make  CFLAGS="-O2 -fomit-frame-pointer" \
CXXFLAGS="-mthreads -fno-omit-frame-pointer -O2"  LDFLAGS=-s \
bootstrap 2>&1 | tee make-out.txt

Now, when I compile gcc, I get this error,

make[4]: Entering directory `/home/bobbybrasko/gcc/svn-head/gcc-builddir-1/gcc'

At c-incpath.c:173 I have,

              /* If the compiler is relocated, and this is a configured 
                 prefix relative path, then we use gcc_exec_prefix instead 
                 of the configured prefix.  */
              gcc_assert (strncmp (p->fname, cpp_PREFIX,
                                     cpp_PREFIX_len) == 0);

The values of the varaiables are,
  p->fname=/c/mingw/include cpp_PREFIX=c:/mingw cpp_PREFIX_len=8

I've also tried with --prefix=/mingw, and that simply changes the fname
to /mingw/include, and it still fails at the same point. If I change the
prefix to C:/mingw, I get totally different errors. I don't think the
Makefile is happy with the : there.

Should I report this as a bug? Is there any easy way someone can help me
debug this further to fix it?

Thanks,
Bob Rossi
