dnl
dnl 	AC_TRY_RUN is a macro that's basically like an if-then-else structure. If
dnl 	the test program (whose text is the first argument) succeeds, the second
dnl 	argument is executed; if the test fails, the third argument is executed; and
dnl 	if autoconf knows it is cross-compiling for another machine and therefore
dnl 	can't run a test program at all, it doesn't try but just executes the fourth
dnl 	argument.  Usually that last alternative should be the most conservative
dnl 	assumption.
