The m4/* files control whether src/config.h contains
'#define inline /* whatever */', and this is what ports
'static inline' to compilers that spell 'inline' in some
other way (e.g., '__inline'), or which don't support
'inline' at all.

MSVC doesn't need to worry about this, as it supports
'static inline'.
