Hello, I've come across a problem with code using gnulib. it attempts to replace strerror with strerror_rpl, resulting in errors like the following:
undefined reference to `rpl_strerror' https://lists.gnupg.org/pipermail/gnutls-devel/2013-November/006594.html This occurs for two reasons: Problem #1: m4/strerror.m4:56-96 this tests for strerror(0). NetBSD (and likely other *BSDs) do not define errno 0. You can see a list of those defined here: http://nxr.netbsd.org/xref/src/sys/sys/errno.h So while strerror is probably 'normal', gnulib chooses to replace it. Problem #2: lib/string.in.h:958-959 # undef strerror # define strerror rpl_strerror it redefines strerror as rpl_strerror, but then does not proceed to define rpl_strerror I do not understand the sed magic that follows, but it does not override this definition.
