/* 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 OMPI/ORTE/OPAL'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 opal_config.h (e.g., via
|
||
|
|
AH_TOP) because they will be turned into #define's by autoconf. */
