[MPICH] ROMIO_PVFS in src/mpi/romio/configure.in

[Wei-keng Liao]

I wonder if this bug for mpich2-1.0.3 has been reported before.

In src/mpi/romio/configure.in, line 1040:
       AC_DEFINE(ROMIO_PVFS2,1,[Define for ROMIO with PVFS])
"ROMIO_PVFS2" should be "ROMIO_PVFS"

On a system that has no pvfs2 installed but pvfs1 (like Jazz @ANL), it can 
cause of application compile error during linking:
    /home/liao/MPICH/lib/libmpich.a(ad_fstype.o)(.text+0x807): In function
    `ADIO_ResolveFileType':
    : undefined reference to `ADIO_PVFS2_operations'
    collect2: ld returned 1 exit status
