[mpich2-dev] error compiling ROMIO's malloc.c in Fedora 15

[Dave Goodell]

This probably is happening because MPICH2 redefines "free", "malloc", and "realloc" when configured with --enable-g=mem or --enable-g=all:

http://trac.mcs.anl.gov/projects/mpich2/browser/mpich2/trunk/src/include/mpimem.h#L236

My guess is that the malloc.h include should be moved above any MPICH2/ROMIO internal header includes.  The rest of us must not have a malloc.h lying around on our systems to cause this compile error...
