Subject: [svn-r11334] Purpose: Feature: checking configure flags (bug #90)

Description:
Some configure flags don't work together.  Configure now exits with
a sensible error message if one of these combinations is specified.

Solution:
The following flags will throw errors:
--enable-cxx and --enable-parallel
--enable-cxx and --enable-threadsafe
--enable-threadsafe and --enable-parallel
--enable-fphdf5 and --enable-fortran

Platforms tested:
mir, modi4, heping
