Not sure what you mean, but those tests aren't skipped on AIXen, HP-UXen, GNU/Linux, most Solaris releases before 10. /lib/cpp is what AC_PROG_CPP may choose, AFAIK it's also the traditional location of the preprocessor. The test whether /lib/cpp doesn't work is meant for Solaris 10, where that preprocessor exists but is too dumb to parse /usr/include/stdio.h, and of course isn't the preprocessor which is used by the compiler: <http://thread.gmane.org/gmane.comp.sysutils.autoconf.bugs/4748/focus=4750> The skip may well be too generous.
