* configure, and b) included in most/all files in PMIx.

/* The only purpose of this file is to undef the PACKAGE_<foo> macros
that are put in by autoconf/automake projects. Specifically, if
you include a .h file from another project that defines these
macros (e.g., gmp.h) and then include PMIX's config.h,
you'll get a preprocessor conflict. So put these undef's here to
protect us from other package's PACKAGE_<foo> macros.
Note that we can't put them directly in pmix_config.h (e.g., via
AH_TOP) because they will be turned into #define's by autoconf. */
