  If that works, great.  Last I looked (a while ago), this didn't seem

  That's a whole lot saner than the "autoconf.h" and "#ifdef HAVE_FOO"
nonsense we use right now.

  I'll see if I can wrap a macro around that example, so there's even
less typing to do:

  AC_NON_STUPID_CHECK_HEADERS(inttypes.h, stdint.h)

--> defines HAVE_*, INCLUDE_*, etc.
