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 macro checks to ensure that the compiler properly supports
|
|
# offsetof(). The PGI compilers had a problem with this macro in some
|
|
# versions of their compiler on some platforms (e.g., 9.0-1 on
|
|
# x86_64). The workaround is to use -DNO_PGI_OFFSET in these cases.
|
|
# A bug report was submitted to PGI support in late June 2009; the
|
|
# problem was apparently a trivial typo in one of their header files
|
|
# and should be fixed in subsequent releases (e.g., 9.0-2?).
