Hmm. It has been in _GNU_SOURCE since the dawn of time and in POSIX since 2008. For non-linux, I peeked at the OpenBSD man page, which says The strsignal() function first appeared in AT&T System V Release 4 UNIX and was reimplemented for NetBSD 1.0. That suggests all of the extant BSDs should have it. MinGW has had the function since 2008. What other hosts do we support? r~
