[svn-r19566] Maintenance: Added -O3 to be used with the C Intel v 11 compilers; set default to -O for all
unknown versions of the C Intel compilers. Modified apple config file to display Intel compiler information. Updated RELEASE.txt notes accordingly. Platfroms tested: jam, amani and dubna (Mac 64-bit) with Intel C, Fortran and C++ compilers.
