Re: forget about my patches for GCC 2.6.1 under VSTa.

Again, i didn't really test my patches.

However, i fetched your patches and failed to cross-link with VSTa 1.3.2
native crt0.o.

I'm cross-compiling with gcc2.6.1 (on host SunOS5.3, with native
gcc2.6.1) First, all of libobjc fails, because of repeated size_t
conflicts

# GCC was configured as follows:
../gcc-2.6.1/configure --verbose --host=sparc-solaris2 --target=i386-vsta --with-gcc --prefix=/netdisk/rigel.2/basile/xvsta --program-prefix=vsta_
echo host=sparc-unknown-solaris2 target=i386-unknown-vsta build=sparc-unknown-solaris2

# i copied include directories (and lib also) of vsta.tz appropriately

# example of size_t error

The /netdisk/rigel.2/basile/xvsta/i386-vsta/lib/crt0.o is a copy of vsta-1.3.2's file.

I suppose i have to patch VSTa crt0.s & crt0srv.s for GCC 2 (actually
for g++ support of destructors and constructors).
