[svn-r9783] Purpose: Bug fix
Description: For HP-UX 11.00, the compiler generates 'floating exception' when converting 'long double' to most of integer types. Solution: Define a macro for all other systems except HP-UX 11.00. Hard set this macro to 'no' in config/hpux11.00 to skip this test for HP-UX 11.00. Platforms tested: modi4, kelgia, fuss
