greater than 3 means 4 at least, not (in my patch)?

I don't know about early gcc 3.4, but the version is shipped with Fedore 
Core3 (3.4.2) does support -fvisiblity. Maybe it would be nice to put a 
HAVE_FVISIBLITY or similar #define into acinlude.m4.in and couple it 
with the -fvisibility test, instead of relying on the compiler version?
