Patch 7.4.1463
Problem: Configure doesn't find isinf() and isnan() on some systems.
Solution: Use a configure check that includes math.h.

dnl Link with -lposix1e for ACL stuff; if not found, try -lacl for SGI
dnl when -lacl works, also try to use -lattr (required for Debian).
dnl On Solaris, use the acl_get/set functions in libsec, if present.
