Actually, AC_TRY_COMPILE is OK, it was only AC_CHECK_HEADERS that barfed on
the warnings.  This means rewriting bits of the AC_CHECK_HEADERS internals
to get the right definitions.  Here's the combined diff.  Or do the
COMPILEs here still need to be LINKs?

I left term.h with AC_CHECK_HEADERS, because otherwise it fails if curses.h
is needed to make it work, which is tested later.

This gets worse and worse.  I can't believe how long I've wasted on this,
and lots of other people have wasted a good bit longer.
