- Add some missing AC_CHECK_SIZEOF's in configure.ac
- Remove some unused variables
- Initialize some variables
- Fix some parameter types
- Cast where appropriate/safe to fix warnings
- Move ompi/mca/common/monitoring Fortran bindings to a separate .c
file so that they can use different #define's than the C bindings,
and therefore compile properly / without warnings.
- Fix signedness discrepancies
- Who knew? Separated these into multiple #if's, instead:
```
// This is undefined behavior
#define HAVE_FOO defined(FOO)
#define YOW (HAVE_FOO && defined(BAR))
```
- Fix some typos in OMPI_BUILD_HOST logic
- Don't "2>/dev/null" in OMPI_BUILD_HOST logic; it just hides errors
