[svn-r1811] Purpose:
New feature
configure.in:
When just --enable-parallel is used, will try to test if MPI and MPI-IO
library codes are linkable. If not, try -lmpi and -lmpio as the most
commonly used library names for them.
Also, set default value for RUNPARALLEL if not set.
Now, for systems, like SGI Crays where there are the system supported
MPI libraries, "./configure --enable-parallel" would configure
correctly.
Configure:
Derived from configure.in via autoconf.
Platform tested:
SGI O2K.
