Your `mpicc -show` output shows there is no bug in mpicc script.<br>
<br>
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. <br>
<br>
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.<br>
<br>
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.<br>
gcc version 4.8.5 20150623 (Red Hat 4.8.5-11) (GCC)<br>
configure:2855: $? = 0<br>
configure:2862:
/home/minsi/git/mpich.git.v3.2/build-gnu-tcp/install/bin/mpicc -V
>&5<br>
gcc: error: unrecognized command line option '-V'<br>

$ mpicc -show
