Which docs of the EMX package do I look in for the error message's?
I'm trying to compile the program 'msgpost.c' and 'mpostp.c' but it keeps
on coming up with these errors :

mpostp.obj(mpostp.obj) error L2029 : 'MsgOpenArea' unresolved external
mpostp.obj(mpostp.obj) error L2029 : 'MsgOpenApi' unresolved external
mpostp.obj(mpostp.obj) error L2029 : 'MsgCloseApi' unresolved external

I'm using bake with these 2 lines 1. mpostp.exe  2. mpostp.c

I expect it's something very simple (I hope) I've not been learning C for
long,and what I have learnt was on a Atari ST :) 
I'd be gratefull for any help I can get,just that I've got quite a few
ideas to add to Mpostp,if only for myself.

Bye Mark
