[mvapich-discuss] MPI version bug in OSU Benchmarks

[Adam T. Moody]

Hello MVAPICH team,
Ignacio was compiling the latest OSU Benchmarks using an older MPI and 
ran into this compile error:

osu_1sc.c: In function 'process_options':
osu_1sc.c:308: error: 'WIN_ALLOCATE' undeclared (first use in this function)
osu_1sc.c:308: error: (Each undeclared identifier is reported only once
osu_1sc.c:308: error: for each function it appears in.)
make[2]: *** [osu_1sc.o] Error 1

This file is missing a #if guard to look for MPI 3.  The following fix 
resolves the issue:

        if ((options.rank0 == 'D' || options.rank1 == 'D')
#if MPI_VERSION >= 3
            && *win == WIN_ALLOCATE)
#else
            )
#endif
