If it works, either you can commit it, or > let me know and I will. 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.
