Heh; I also hate it when things change underneath me.  :-)
Regardless, you should consolidate.  The name doesn't matter much, and
loadmk was in first; so you should stick with loadmk.  It's probably
fine if you swap in your implementation, but make sure you cc the
author of loadmk when you submit the patch.

Add the gunzip decl to the header please.  Submit as a separate patch.
 For extra credit; include a patch to remove all the spurious extern
gunzip() decls scattered about the various .c files.  :-)

Heh; only ugly because the if() is longer than 80chars and spills over
3 lines.  :-)
