config/ directory. We split them apart a while ago in the hopes that it would simplify things, but it didn't really (e.g., because there were still some ompi/opal .m4 files in the top-level config/ directory, resulting in developer confusion where any given m4 macro was defined). So this commit consolidates them back into the top-level directory for simplicity. There's still (at least) two changes that would be nice to make: 1. Split any generated .m4 file (e.g., autogen-generated .m4 files) into a separate directory somewhere so that a top-level -Iconfig/ will only get our explicitly defined macros, not the autogen stuff (e.g., with libevent2019 needing to get the visibility macro, but NOT all the autogen-generated inclusion of component configure.m4 files). 1. Change configure to be of the form: {{{ # ...a small amount of preamble/setup... OPAL_SETUP m4_ifdef([project_orte], [ORTE_SETUP]) m4_ifdef([project_ompi], [OMPI_SETUP]) # ...a small amount of finishing stuff... }}} I doubt we'll ever get anything as clean as that, but that would be the goal to shoot for. This commit was SVN r27704.
