Provide a fallback timercmp() definition (PR misc/59543)

timercmp() isn't a standard function (macro in this case)
so isn't guaranteed to exist on some random system that
we need to be able to build this on (since it is part of
the NetBSD tools setup).

So just provide a local copy of the definition, used in
the event that nothing else has already defined it.

achVendID is an array not a pointer so it is always "true".
avoid clang warnings by not testing it.

Build fix. don't provide a conflicting declaration of FcObjectTypeHash and
FcObjectTypeLookup. they're defined in fcobjshash.h included just after.

Undo a local change now that our scandir() signature has been fixed.

Switch #pragma message(...) to #warning so it actually does anything.

Avoid __UNVOLATILE here, just inline the cast. We don't have
src/tools/compat's header here.

If you are going to test an enum value for equality with -1,
and -1 is out of range for the enum type,
then at least cast the -1 to the appropriate enum type.

Deal with the limited range of VAX floating point numbers when compiling
