Added compiler versions for mpich to settings file and configure summary.
For make installcheck, compile and run installed examples using the installed scripts.  They were being compiled but not run.
Add Fortran2003 examples to the run-ex-fortran script when fortran2003 is enabled.
Set flag to -O3 in production mode for Intel compilers other than those with specified other settings.
Gentoo patches:
    Remove unnecessary setting of LD_LIBRARY_PATH from configure.
    Prevent potential array subscript out of bounds error in perform/pio_engine.c and sio_engine.c.

Tested with h5committest on jam, koala, ostrich and platypus, on emu and kite, and parallel tests on jam, koala and platypus with mpich built with gnu 4.8.2 and with intel compilers.
