SystemV has standard library functions for this. Qpopper can use them if
compiled under Solaris. So for qpopper, I just created those functions myself.
It might be a good idea to put them in a small (not shared) library, so
other programs can use them. And the changed required would not be
#ifdef debian, but #ifdef SYSV. Much better IMO.

If you have access to a sysv system (like Solaris 2.x) try "man maillock".
In fact those functions are, in Solaris at least, in a seperate library
called "libmail". We could use that as an example. Perhaps we could even get
it into GNU libc, that would make it even easier.

I'll work on that next week, for I'm going on a three day bike trip with the
local pub's motorbike gang tomorrow :)
