[svn-r6899] Making changes to windows configure script related to r6852. (1) All *F90* vars are now renamed as *FC* (2) The complete set of fort integer models is now represented by a new var - *ALL_INTEGER_MODELS and the older *INTEGER_MODEL var is now used similar to other dt MODELs

[svn-r6898] fix to r6897 so that top-level configure's enable-option-checking is followed in the subconfigure.

[svn-r6897] disable option checking in mpich2's configure of subpackage (no more warnings of unrecognize --enable or --with options) so it behaves the same as AC_CONFIG_SUBDIRS.

to connect back to the server, ask the user to check for
firewalls. Also, added some code to error out on the server side if
the proxy terminates badly.

bootstraps, pass a NULL stdin socket.

versions of ssh seem to freak out when the stdin socket is
closed. This issue showed up on ranger.

external bootstrap servers.

[svn-r6887] Replaced strerror with MPIU_Strerror in a whole bunch of places (basically everywhere, but romio, mpe, windows netmods, etc.).  Reviewed by goodell@

method to avoid more bugs in the future.

RMK.

Cadence. Also moved the LSF RMK functionality to the bootstrap server
as well.

external script based bootstrap servers to a common directory, since
they share a lot of code. This commit also fixes a bunch of bugs in
the configure step which was not allowing the user to pick the
non-default bootstrap server easily.

rewriting it in configure.in

[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-r6873] added -nativelinking option so the builddir version of MPI wrappers can be used subpackge configure.in to replace the 2nd compiler, i.e. BASE* compiler in test/mpi/configure.in.  -nativelinking is an internal option, so don't show it on -help output.

This bug doesn't show up on many platforms, since sizeof(int)==sizeof(long)
in many cases.  On OS X 10.6, with 64-bit compiles (the default), the sizes
are 4 and 8 bytes, respectively.

[svn-r6869] moved FUNCNAME/FCNAME macros before the comments for top-level MPI functions because the documentation generator script expects the function prototype to immediately follow the comments

[svn-r6868] Added details about what nearly meant in the explanation of ALLFUNC.  This draws on the analysis of the thread nature of the MPI routines
