should be used only in headers and between INLINE_HEADER_BEGIN
and INLINE_HEADER_END. No need for ‘inline’ here.
* src/alloc.c: Omit unnecessary static function declarations.
Don’t use ‘inline static’ as the C standard says that keyword
order is obsolescent. Anyway, no need for ‘inline’ as compilers
inline without it well enough.
These don’t need to be extern, even with -flto, since
their addresses are taken.
