no longer relevant with the current state of the configure script, and

to just link with libmpich.so, and the remaining libraries are
dynamically loaded. This support is only for shared libraries at this
point (static library support might require libtool). Also, this is
experimental, as it has a bunch of gotchas that we cannot handle
unless we reimplement libtool.

added a new test PAC_F2C_ATTR_ALIGNED_SIZE to replace PAC_C_ATTR_ALIGNED to determine the alignment of Fortran common block as seen in C.  Also added a switch, --enable-multi-aliases, to disable the feature just in case something goes wrong.

[svn-r7054] Add support for disable-rpath in configure to allow building shared libraries and scripts to support knowning where the shared libraries were installed (the best for most users) or, with --dsiable-rpath, requiring the use of LD_LIBRARY_PATH, which is best for building libraries to be installed in other locations

[svn-r6874] Removed the 2nd set of compilers in test/mpi/configure.in, i.e. BASExx, which are basically replaced by "mpixx -nativelinking".  This greatly simplifies the test/mpi/configure.in because there is no need to swap between 2 set of compilers and compiler flags, CC/CFLAGS vs MPICC/MPICC_CFLAGS, for every languages in every tests.  Also replaced all AC_TRY_* by AC_*_IFELSE and removed all references of AC_FD_CC, updated the configure.in to autoconf-2.6x style.  Removed AC_SUBST(autoconf precious variables)....

[svn-r6853] fixed the typo in MPICH2_BASE_* which should be MPICH2_BASE* in configure.in.  (These variables are exported to test/mpi/configure.in)  Fixed (temporary) the
incorrect setting of BASEF77 when FROM_MPICH2=1 in test/mpi/configure.in.

[svn-r6852] Initial deposit that removes the AC_LANG=[Fortran 90] and replaces it by AC_LANG=[Fortran] which is officially supported by autoconf.  The replaced PAC macros in aclocal_fc.m4 is also rewritten by replacing all use of AC_TRY_* by AC_*_IFELSE style as recommented by autoconf.  The change also removes some old autoconf macros date back to at least 2.13 as in aclocal_cross.m4.  The change that users see is to use FC/FCFLAGS instead of F90/F90FLAGS which will no longer be supported.  This also includes some misc fixes that allow mpif90 to access mpi.mod during build process....

This is actually several logical changes, but they are very difficult to
separate into individual commits because of how tangled the old macros
were.  Some of the changes are:

- general macro cleanup: do{}while(0) and whitespace issues
- add support for compiler-assisted thread-local storage (TLS)
- make MPID_Thread (e.g. pthread) TLS macros easier to understand and use
- drop non-portable parentheses from MPIU_ISTHREADED macro
- eliminate the MPID_CS_* family of macros which were simultaneously
  complementary to and in conflict with the newer MPIU_THREAD_CS_*
  macros

These channels are old and have been deprecated for a while.  Their
presence is hampering PMI API development, so I have removed them.
These were the only channels seriously using the "process locks" code,
so that mess has also been deleted.  The only remaining useful
functionality (MPIDU_Yield) has been moved to the OS wrappers.

cleans up some of the checks and adds everything to LIBS, instead of

It's still possible for some platforms to not like this format (perhaps
they don't have symlinks, etc).  But this is at least an improvement.

Previously flags to AR were fixed by simplemake to be "cr".  With this
change this can be controlled by configure/make via the new AR_FLAGS
precious variable.  On darwin using "Scr" shaves ~10% off the normal
build time.

This is a minor, nibbling around the edges fix.  The real fix is to
rework all of the linking in MPICH2 so that parallel builds are possible
and only a single invocation of AR/RANLIB occurs for each library that
we produce.

[svn-r6268] Added checks for multiple aliases support from C compiler.  setbot.c.in is a real item in svn instead of generated from buildiface.  Modified mpif.h.in and setbotf.f.in to allow (better) multiple aliases support.

In the compiler wrappers we force the linker to use the "flat namespace"
model instead of the default "two-level namespace" model.  If we add
dynamic library support for MPL and OPA then we can probably drop this
option again.
