Re: MPE Port

[Mark Klein <mklein@dis.com>]

Explanation:

MPE/iX is a late binding OS, so simply compiling and linking a test
program to prove the existence of various routines won't work. I've
built a customized autoconf where the ac_link macro also attempts to
run what it links. It does so in a fashion such that if the final
bind is successful, then the program will not actually be run 
because in most cases, it will fail, which will still give a 
false negative. 

This script simply finds all cases of configure.in scripts that
are autoconf versions, not Cygnus versions.
