If you want to specify pgcc/pg++ as the compiler to build something
that uses autoconf configuration, the "how to run the preprocessor"
test will reject the option "pgcc -E" because of the warnings about
unused libraries. This then means you get the wrong headers in *some*
of the tests and you may end up with the wrong configuration.
The fix is simple suppress the libraries if the -E flag is used:
