Is there a pre-canned AC macro or other reliable means of testing for compiler attributes? I have an awful lot of code that looks something like this: void *myfunc(char *myvar #ifdef __GNUC__ ) __attribute__((malloc)); # else // ifdef __GNUC__ ); #endif // ifdef __GNUC__ and it has to the potential to get a lot worse if I have to start testing for what version of GNUC we have to use a new attribute. While I realize this could all be done with CPP macros it occurred to me it would be nice to have this information available from config.h. -J --
