It was really chosen for Red Hat compatibility, because I doubt companies
like Netscape will make their packages for something non-commercially
backed. And last time I've tried mozilla it was behaving pretty badly on
sparc/sparc64. I think this is solvable by symbol versioning in glibc 2.1,
so we can keep the compatibility...

BTW: gcc 2.7.* is really completely unusable whenever a program uses long
long, you just cannot trust them. If I remember well, it miscompiles e.g.
unsigned long long l; void foo(void) { l += 0x80000000ULL; }
BTW2: Don't expect 64bit very userland soon, there are really many places where
egcs has to be fixed/optimized before 64bit userland can be done, and at the
moment we're hacking the kernel to manage as much as possible into 2.2 (like
A5000 support, E10k, and stuff like that).
Cheers,
