But it's non-portable.  GCC extensions are not in the the 
ANSI or ISO standards, and no other compiler can be expected
to support them.  Some of us have to deal with other compilers
(there's no GCC for the Mac, for instance, and I'm informed
that people using several other machines don't use it because 
the code generation leads to large executables).
