[mpich-discuss] mpich2&open64 shared object compilation bug&fix

[Pavan Balaji]

Your patch below is to configure (not configure.in) which is 
auto-generated.  The first step I'd recommend is to try out 
mpich2-1.5rc1.  That uses libtool for shared library support.  That'll 
at least confirm whether libtool supports open64 or not.  If it doesn't, 
then a patch would be required for libtool.
