+1 for modern C.

Those are not correctness problems.  Compilers with non-optimal or
missing 'inline' do belong together with compilers without working int64.
We may spend some effort to be able to compile on them, but they
should not affect our coding style.

'static inline' is superior to macros because of type-safety and
side-effects avoidance.  I'd suggest event removing any HAVE_INLINE
ifdefs and let autoconf undef the 'inline' if needed.  Less duplicated
code to maintain.  The existence of compilers in active use without
working 'inline' seems quite hypothetical these days.
