Hi,
Ah, now I got you. Hmm, well, I see here no advantage in adding
another macro to check for an macro. As in code of libstdc++ there is
actual no use for those new ones.
To be clear, I didn't personally invent those, but I'm still finding a
bit strange doing only for mingw something completely different,
considering in particular that the autoconf procedure is run *anyway* on
mingw too...
Nevertheless, for some error-numbers (eg. EAFNOSUPPORT, EBADMSG, etc)
- which are socket API related - there is no constant define in
errno.h (and never will be). So code to emulate this would be still a
manual thing in error_constants.h header AFAICS (if we plan to support
them for mingw targets).
Once more, I don't understand: didn't you suggest changing *only* ENOSPC
and EPERM? Why are we now discussing other error-numbers like ECHILD,
EAFNOSUPPORT and EBADMSG? Are the latter defined in errno.h? In that
case, please use [GLIBCXX_CHECK_SYSTEM_ERROR] for now. We can always
simplify things at a later time.
Paolo.
