[mpich-discuss] mpicc -V broken

[Min Si]

Your `mpicc -show` output shows there is no bug in mpicc script.

I tried to configure mpiblast with MPICH v3.2 release. I see a slightly 
different error reported if searching `mpicc -V` in config.log, but the 
configure is completed without any error.

I think the configure just tries to get some compiler information 
through common options such as `--version`,  `-v`, or `-V`.  But it does 
not break the configure if any of those options is unsupported. So you 
can just ignore this error message. Please let us know if you find other 
problem break the compiling.

Btw, here is the error message on my side. I think we see different 
errors for `-V` option just because of a different GCC version.
gcc version 4.8.5 20150623 (Red Hat 4.8.5-11) (GCC)
configure:2855: $? = 0
configure:2862: 
/home/minsi/git/mpich.git.v3.2/build-gnu-tcp/install/bin/mpicc -V >&5
gcc: error: unrecognized command line option '-V'
