It also has a process spawning facility, loosely inspired by posix_spawn.
The goals of libfixposix and gnulib might seem superficially similar, but 
they're a bit different:

1) I've written it as support for a CommonLisp 
project(https://github.com/sionescu/iolib), and since in Lisp we load shared 
libraries through dlopen() and bind to the symbols through dlsym(), libfixposix 
must be a shared library and it exposes function wrappers for many C macros, 
e.g. CMSG_FIRSTHDR & co.

2) In some cases, like for lfp_spawn(), I want to supersede POSIX functionality 
not bridge over differences. At some point I started reimplementing 
getaddrinfo() & friends because the differences between GNU Glibc, FreeBSD, and 
OSX were driving me mad, but then I just wrote it in Lisp

3) In the Lisp community (L)GPLv[23] are generally considered unacceptable so I 
settled on the Boost Public Licence
