Minor compile bugs, and LAM update

[Ben Webb]

The recent release of mpiexec-0.67 made me notice two things...

1. If your PBS headers are installed in /usr/include, the mpiexec
   Makefile adds -I/usr/include to a gcc invocation. This is a bit dodgy
   as it alters the search path (if gcc has modified any system headers,
   and put them in gcc-specific directories, this use of -I will cause
   the old, buggy, headers to be used instead). gcc 3.1 complains about
   it, anyway. I use the attached patch to work around this.

2. The LAM patch is out of date. An updated version is available at
   http://bellatrix.pcl.ox.ac.uk/~ben/pbs/lam-mpiexec-tm.patch. (The
   version included with mpiexec won't, I think, work at all, due to a
   bug in my use of waitpid() for hboot's child processes.) I would have
   noticed this earlier except that there appears to be a problem with the
   mpiexec CVS server. Whenever I do a "cvs -z3 update -dP" I get:-

in.cvsd server: Updating .
in.cvsd server: Updating patch
in.cvsd server: failed to create lock directory in repository
`/cvs/mpiexec/patch': Permission denied
in.cvsd server: failed to obtain dir lock in repository
`/cvs/mpiexec/patch'
in.cvsd [server aborted]: read lock failed - giving up

This doesn't look like a problem at my end...
