Thanks for testing it. I installed this patch.

* lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
innocuous variant befor including <limits.h> or <assert.h>. This
works around a bug reported by Albert Chin: HP-UX 11i
(and earlier versions) have a <limits.h> that declares
gettimeofday and many other functions.
