Maybe,
the idea was to have POSIX in X11, and use glibc as base (or ulibc if you like).
import of nice ideas via gnulib (or like) would allow any POSIX system to compile.

you can sustitute POSIX with SUSVx if you like. The strength of X11 is in it compatibility
to all the different implementation and i think gnulib is a nice tool to help with that goal.
