[svn-r6413] Purpose:

bug fix, features.
Description:
    removed the cache of sizeof_long since it varies between 32 and 64 bits.
    Set xlc and mpcc_r as the default compiler for serial and parallel modes.
    Added -D_LARGE_FILES by default to support large file size.

    Added gcc gnu-flags when gcc compiler is used (not working yet.)
Platforms tested:
    Tested in Copper only since that is the only AIX machine on site.
