Fcntl implementation (mimicking Perl 5)
For this module, I'm trying to give you a module which has the native
definitions for constants for a given OS, generated from
C headers but
available in a pure Perl 6 module. In order to do this, I've written a very
C program which appends Perl 6 code to a template, and then that's
what you use. I've also written a small test program that allows me to verify
the values are what C thinks they should be when I send them back in.
For more details, read the POD.
