[mpich2-dev] GPL bits in MPICH2

[Pavan Balaji]

The autoconf macros come with a special license that do allow us to 
distribute configure scripts generated from them without being 
restricted by the GPL license.  Here are the lines of interest:

# As a special exception, the respective Autoconf Macro's copyright owner
# gives unlimited permission to copy, distribute and modify the configure
# scripts that are the output of Autoconf when processing the Macro. You
# need not follow the terms of the GNU General Public License when using
# or distributing such scripts, even though portions of the text of the
# Macro appear in them. The GNU General Public License (GPL) does govern
# all other use of the material that constitutes the Autoconf Macro.
#
# This special exception to the GPL applies to versions of the Autoconf
# Macro released by the Autoconf Macro Archive. When you make and
# distribute a modified version of the Autoconf Macro, you may extend this
# special exception to the GPL to apply to your modified version as well.
