It's really a pain that this macro exists IMHO. The user should not
know about it, it should be hooked to something more standard,
perhaps simply AC_PROG_CC.

Sorry, I really thought we had something for streerror, but it's only
strerror_r. And anyway you demonstrated it's not a solution since
there are other functions living in there.

| Not in autoconf itself, but lots of GNU programs use AC_ISC_POSIX:
| A2ps, Bash, Bison, CVS, Diffutils, Enscript, Gzip, ...,
I was referring to other functions � la strerror. I don't know for
the others, but the a2ps maintainer put it in there just in case, w/o
understanding if it's relevant or not :) Precisely because this macro
and other system related macros are obscure, with fuzzy semantics.
