[mvapich-discuss] fail to link with mvapich2-1.2p1/mvapich2-1.4rc2

[Manhui Wang]

Dear MVAPICH2 developers,
       Following last mail, I tried to see whether it is possible to
make some change in Molpro. But it seems to be impossible since Molpro
directly calls these functions, which are from yacc or bison libraries.
This means these name conflicts with those in yacc or bison libraries. I
have made two small patches(see files attached) for mvapich2, with these
patches Molpro works fine with Mvapich2. I would be very appreciated if
you can  include these changes (probably you will consider more changes
to avoid conflicting with other programs, but this works for molpro at
least) in the mvapich2 development version at your earliest convenience.
So I can test the updated mvapich2 before the final release.

Thank you very much.
Manhui
