Hmm, this worked yesterday:
gcc version 4.0.0 20041201 (experimental)
-Werror should not be there.
In fact in my compiling I don't get -Werror:

Can you try configuring with an absolute path?

[Bug ada/18773] [4.0 Regression] GCC terminates on warnings compiling ada/raise.c

But I do now, this is just wrong.
In fact it was caused by:
2004-12-01  Mark Mitchell  <mark@codesourcery.com>

        * Makefile.in (WERROR): New variable.
        (STRICT2_WARN): Use it.
        (STAGE2_FLAGS_TO_PASS): Likewise.
        * config/i386/x-mingw32 (WERROR): Add -Wno-format.

Ada's Make-lang.in uses WERROR which seems wrong.
I might submit patch to fix the problem.
