If the code depends only on the operating system, let's use a #if for the operating system, not for the compilers (__USLC__). Because the day clang gets ported to that operating systems, the condition would not work any more. https://sourceforge.net/p/predef/wiki/OperatingSystems/ says that _SCO_DS can be used to test for SCO OpenServer. It seems that you say that __SCO_VERSION__ works as well. So let's use one of these. Bruno
