Hi all.

I have a problem installing a gcc-3.2 cross-compiler
  under Cygwin(cygwin-1.3.22.tar).

../configure --target ae32000-elf --prefix=/usr/local --enable-languages=c,c++ --with-gnu-as --with-gnu-ld --with-headers=...  --with-newlib

# (host : i686-pc-cygwin)

When compiling the gnu-regex.c , error message is the following.
...

When compiling at the linux environment, it's no problem.

How does it slove?
Please give me some hits...

If anybody could shed some light on the subject I would be very grateful.

Cheers,

Djkim.
