Comment 1 for bug 1073932

I guess the big question is, why we provide our own version of pdep, as the README of the files in our source notes:

These files are directly copied from the Lua distribution, with the
exception of lzio.h, which is s/lua{ZM}/pdep/g and has an include removed.

SirVer, I assigned you, as you hopefully know, why we ship our own pdep and how to handle the problem.
