No, that's a bug in the compiler. In cppinit.c:set_lang, dollars_in_ident is only initialized from lang_defaults::dollars_in_ident, ignoring the global variable dollars_in_ident. OTOH, the global variable dollars_in_ident is initialized with DOLLARS_IN_IDENTIFIERS if it is not explicitly specified on the command line. So outright copying the global variable into CPP_OPTIONS would not be correct, either, as it would ignore the choice of language. I believe these mechanisms (language default, target default, command line) need to be combined somehow. Regards, Martin -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
