defining "inline" not to "__attribute__ ((__always_inline__))", but to
"inline __attribute__ ((__always_inline__))" should have the same effect,
but my gcc 3.3.1 emits much fewer warnings with the latter
(That is because static inline functions for example in ffmpeg are implemented
in the header, but not used in every file that includes this header. Now
gcc reports unused static functions with a "defined but not used" warning
unless they are static inline. The former define would have dropped the inline
and therefore triggers those warnings.)
