I configured, built and installed from gnulib git; no problem there.

I ignored this problem. My principle interest at present is to build
the luaposix Lua bindings for POSIX APIs, so any version of libposix
makes things better and is hence "new enough".

Since luaposix doesn't use autotools, this simply consists of adding
-I/usr/local/include/libposix and -lposix to appropriate points in the

I then get the error:

cc -fPIC -I/usr/local/include -I/usr/local/include/libposix -pedantic

The first error is eliminated by passing -std=gnu99, but maybe this
should not be necessary? The second seems indeed to be a case of
glob-libc.h not being installed.
