The only way to do this is to test the compiler directly by attempting to compile a tiny test program, and then build the header file depending on the success or failure of the compile. But I am not a PC programmer, so I don't know if there is a scripting language powerful enough to accomplish it. -- Kevin Cline [ comp.std.c++ is moderated.
