Failure building Ada on i686-pc-mingw32

[David Gressett]

Development environment:
i686-pc-mingw32 on Windows 2000 Pro SP4 (Athlon processor)
MinGW 3.2.0 (gcc 3.4.2 mingw-special)
Msys 1.0.10

../gcc-4.0.1/configure   --verbose --with-gcc --with-gnu-ld 
--with-gnu-as --host=mingw32 --target=mingw32 --prefix=/mingwlocal  
--enable-threads  --disable-nls --disable-win32-registry 
--disable-shared --enable-sjlj-exceptions --enable-languages=c,ada

Ada fails in stage1; the offender is gnatbind.exe. It crashes even if 
invoked with no command-line arguments. Gdb provides the following 
information:

(gdb) run
Starting program: C:\gcc401install\gccbuild\gcc\stage1/gnatbind.exe

Program received signal SIGSEGV, Segmentation fault.
0x004034b7 in __gnat_install_SEH_handler (ER=0xffffffff)
    at ../../gcc-4.0.1/gcc/ada/seh_init.c:219
219       ((int *)ER)[0] = (int)ptr;                       /* previous 
handler */
