As Andreas said, GCC seems to be getting lazier lately. (Actually, my
knowledge bits were based on a recent experience. -Winline told me, to
my surprise, that some short function wasn't being inlined. But (after
digging and finding this __inline__ __attribute__ thing) forcing the
compiler to do it confirmed the compiler's guess: it wasn't worth the
while (the whole thing was faster by about 1 percent, which I consider
to be noise).
This behaviour was consistent across several gcc versions (2.95 through
3.some).
