It doesn't understand the named ... variant, which I suppose is more recent tinkering. Use the older __VA_ARGS__. Also I didn't think your use of ## was correct in any case (you can only concatenate things that produce a valid token). It looked as though #define err(exitcode, format, ...) \ errx(exitcode, format ": %s", __VA_ARGS__, strerror(errno)) etc might work.

There have been many fixes to BWK's code since then. If you're going to start over, it should be done from his current code, available from his Princeton home page. Arnold

> Have the MKS sources ever been released? I don't believe so. I think they were the basis for z/OS, which is a POSIX environment on top of IBM's MVS. The MKS awk made its way out into the world via Solaris, which for some reason chose that code base, instead of a more recent version of BWK's awk, for their POSIX awk. Quite some time ago I ported it to Linux; it took an hour or so. It'd take more work to make it generally portable, which I never bothered to do. Arnold

I've looked at the C99 and C1x standards and both describe pre-processor ... and __VA_ARGS__ as Plan 9's cpp implements it, and neither allows the identifier ... syntax.
