I found myself fixing a project that used printf("%m") to work on BSD.
That particular project is incompatible with GPL, so it would not
benefit from gnulib, but it made me wonder if there is any interest in a
gnulib module that provides guaranteed %m support on all platforms. It
doesn't fit in the existing printf-posix module, so we'd have to make a
new printf-gnu module (presumably GPLv3+, rather than trying to be
LGPLv2+, as an LGPL project is better off sticking to the bare-bones
printf-posix). Or is better to just document in
doc/posix-functions/*printf*.texi that %m is not portable, and that the
recommended workaround is to manually pair "%s" with strerror(errno),
rather than relying on gnulib.
