2.95 yes, actually even with -O3 -fomit-frame-pointer
3.0 don't know.

Don't know, but will try it if I get a chance.  I used to be able to
try different compilers on Debian project machines relatively easily
by:

dpkg --fsys-tarfile <needed debs> | tar xf -
export GCC_EXEC_PREFIX=$HOME/usr/lib/gcc-lib/
export LD_LIBRARY_PATH=$HOME/lib:$HOME/usr/lib
export LIBRARY_PATH=$HOME/lib:$HOME/usr/lib
export C_INCLUDE_PATH=$HOME/usr/include
ln -s gcc-??? usr/bin/gcc
export PATH=$HOME/usr/bin:$PATH

but this isn't working of late anymore, due to

1) dependencies on latest libc, which in turn depends on latest ld.so,
   which I can't install as a user
2) oddities with stdlib.h installed with the above procedure.  Some
   defines are missing.

Take care,
