[svn-r499] enabled VPATH build by setting TEXINPUTS/BIBINPUTS so latex/bibtext/dvipdfm can locate remote source files.  Removed symbol link hacks

[svn-r492] Hack fix to the datatype bug reported by Microsoft. The problem was in the datatype code, where the function counting the number of contiguous segments was optimized for index and block index types, by merging neighboring contiguous segments, while the actual flattening code was not. So, the estimated count was always smaller than the actual count as seen by the flattening code. I've currently disabled optimizations in the count functionality. The correct way to fix this, however, is to add the same optimizations in both places.

[svn-r490] Disabling the command tests, since they are not supported by all process managers, and are not required to be supported by MPI.

[svn-r489] removed all common used env variables, e.g. CFLAGS, LDFLAGS, FFLAGS..., from being used in mpiXX wrappers

[svn-r486] Fixed some problems with the --disable-compiler-optimizations option. There are still some errors with respect to the recursive usage of the options.

process stats the file (stat, lstat, stat parent dir), then broadcasts the
result to everyone else.   This optimization won't work in the case where a
file is "UFS" on one process and "NFS" on another, so we just don't do it this
way if NFS is enabled.

[svn-r477] Initializing some additional variables during their declaration. This doesn't hurt MPICH2, but eases OSU's MVAPICH2 integration.

[svn-r476] 1) Adding -envlist option to mpiexec (2) Set the default value of number of procs to launch to 1 in mpiexec

self-contained lustre-only pieces.

[svn-r466] Updated the user and install guides to automatically take the version number from maint/Version.

[svn-r463] The CHANGES file should point to the 1.0.7 branch so that we don't need to keep updating this file for every RC or patch release.
