Removed all instances of macro INLINE, as this is showing up now

as failing on certain compilers.  This undoubtedly reflects some
change in gcc or the OS setup, but since modern compilers should
be able to figure out for themselves when to inline a subroutine
(or not), the inline hint is somewhat arcane and unnecessary.
