Yes, but the compiler also defines some - some are internal (compiled
into gcc when it was built), some are based on command line switches
(try adding -march=i686 and see what changes) and others are from the
compiler's specs file - on a RH7.3 box, it's in:
The "i386-redhat-linux" is the machine triplet used to configure gcc,
"2.96" is the version number.
