Or, as this is already gcc specific, you could just use the predefined
macro __USER_LABEL_PREFIX__, which expands to a string; for instance
#if defined(__GNUC__) && __GNUC__ >= 3
extern Arg no_arg __attribute__((
#ifdef __MACH__
// Mach (or at least OS X), doesn't support strong aliases, so make it
// weak. This is a smidge less safe in theory (conceivably, someone
// could override this symbol in their own binary), but perfectly ok.
weak,
#endif
alias(__USER_LABEL_PREFIX__
"_ZN7pcrecpp2RE6no_argE")));
#endif
[in case you haven't seen it before, I should explain that two
adjacent strings will be concatenated by the compiler]
