[svn-r26591] Description:

    Bring r26492 from autotools_rework branch back to trunk:

    Remove the FP_TO_ULLONG_ACCURATE and FP_TO_ULLONG_RIGHT_MAXIMUM
macros/defines, which were added to address problems with older PGI
compilers and HP-UX systems and are no longer supported.

Tested on:
    Linux/32 2.6.18 (jam) w/serial & parallel
    (daily tested on branch for >1 week)
