Changes to VT:
	- fixed build error reported in http://www.open-mpi.org/community/lists/users/2013/01/21081.php:
		- removed typo
		- added configure test for declaration of the global 'environ' variable in unistd.h
Fixes the definition of the first fragment and does not assume that first frag has offset_into_user_buff equal to zero. This fix should be added to cmr:v1.7.1:reviewer=pasha
Minor line-break fixes.
Add notes/warnings about Java.
Use a process name instead of a name list in bcol_basesmuma
Fix fortran issues when there's no fortran compiler.
Good suggestion from Ralph: it's not complete ''now'' (it ''may'' be in
the future).
Based on a bug report and suggested fix from Darshan maintainer Phil
Carns, change to use access(.., F_OK) instead of stat() to check for
the presence of files.

Also remove redundant check for FAKEROOTKEY, and update all comments
to match.
Fix from Jed Brown for fairly obvious typos.
New sm BTL initialization take two. This approach is pretty simple. Instead of
using the modex or RML to share sm initialization information, have node rank 0
create a file containing initialization information in a well-known place. Then
during add_procs, the rest of the node processes requiring sm BTL initialization
will just read from that file to complete their initialization.
Updates for Automake 1.13.x.  Without these changes, Automake 1.13.x
will error out, due to use of the
previously-deprecated-and-now-removed AM_CONFIG_HEADER macro.
Along with the Automake 1.13.x changes in r27790, rename these third
party configure.in scripts to be configure.ac so that Automake stops
complaining about them.
Trunk version of r27792 (cmake filename changed between trunk and
v1.6).  This is likely a useless commit, because Windows support will
likely be deleted in the trunk eventually (and is almost certainly
currently broken), but I figured I'd do my due diligence in
back-porting from v1.6 on the small, small chance that someone
resurrects the cmake/Windows support on the trunk.
In short: this commit removes a bunch of code by switching the opal
event framework to STOP_AT_FIRST, and then moves a bunch of
side-effect-inducing code in the libevent2019 configure.m4 up to
POST_CONFIG.

== More detail ==

Change the event framework from STOP_AT_FIRST_PRIORITY to
STOP_AT_FIRST.  This means that only one component can win (vs. all
STOP_AT_FIRST_PRIORITY, in which multiple components of the same
priority can all win).

You still need to ensure that there are no side-effects from the
winner, however, so check for winning during POST_CONFIG, and set
things like the base_include there.

This simplifies the configury quite a bit -- you don't have to assume
that mulitple components can win: zero or one components will win.

Also change the libevent 2019 priority to 50 so that some other
(developer-specific/local) component could win, if it wanted to.
Remove debugging message.
Similar to r27794, simplify the hwloc framework by changing it to
STOP_AT_FIRST.  And move the side-effect-inducing code in
hwloc142/configure.m4 up to POST_CONFIG.

Also change the priority of the external hwloc component to 90 so that
it is evaluated before the internal component (as a direct result of
changing to STOP_AT_FIRST).
Update the embedded hwloc from v1.4.2 to v1.5.1.
Cleanup new hwloc install - remove build products that were accidentally included in the commit, remove non-existent file from Makefile.am
Fix a typo.
