Re: [GENERAL] [PATCH] Better way to check for getaddrinfo function.

That's odd. Is getaddrinfo a macro on Tru64? If so, the appropriate
patch would probably make the test look more like the tests for finite()
and friends:

dnl Cannot use AC_CHECK_FUNC because finite may be a macro
AC_MSG_CHECKING(for finite)
AC_TRY_LINK([
#include <math.h>
double glob_double;
],
[return finite(glob_double) ? 0 : 1;],
[AC_DEFINE(HAVE_FINITE, 1, [Define to 1 if you have finite().])
AC_MSG_RESULT(yes)],
[AC_MSG_RESULT(no)])
