[mvapich-discuss] mvapich2-1.7a: configure: error: Unable to convert MPI_SIZEOF_AINT to a hex string

[Jonathan Perkins]

Thank you for the suggestion Anthony.  We'll look into improving the
checks for LiMIC2 as well as some other libraries which are handled
similarly.

Regarding the autoconf version.  We used the version of autoconf that
was shipped with Fedora 14.  This has been patched to resolve these
issues and we haven't seen any problems using it.
