need help compiling gcc for Windows

["Sheryl Canter" <sheryl at permutations dot com>]

The configure is completing correctly (as far as I can tell), but the
build didn't work. It works up to this point:

------------
Bootstrapping the compiler
make[1]: Entering directory `/c/gcc-objdir/gcc'
make AR_FOR_TARGET="ar" \
        RANLIB_FOR_TARGET="ranlib" \
        CC="gcc" libdir=/c/gcc-3.3.1/lib LANGUAGES="c " \
        CFLAGS="-g " MAKEINFO="makeinfo --no-split" \
        MAKEINFOFLAGS="" COVERAGE_FLAGS=
make[2]: Entering directory `/c/gcc-objdir/gcc'
./gengtype
/c/gcc-srcdir/gcc-3.3.1/gcc/../include/ansidecl.h: No such file or directory
make[2]: *** [s-gtype] Error 1
make[2]: Leaving directory `/c/gcc-objdir/gcc'
make[1]: *** [stage1_build] Error 2
make[1]: Leaving directory `/c/gcc-objdir/gcc'
make: *** [bootstrap] Error 2
------------

That file spec with the error message looks a little strange, but it
correctly points to the file. ansidecl.h can be found here:

/c/gcc-srcdir/gcc-3.3.1/include/ansidecl.h

Any idea why the build didn't work? How do I correct this problem?
