Well I know it sounds crazy, but I want it in DJVerify to detect mixed 
installations. That's a common problem (people saying: Why RHIDE pass only 128 
bytes to gcc?). With RHIDE and DJGPP itself we can just check the *.ver files, 
but if the user deleted the .ver files we will fail and with make and other 
tools isn't so easy because the same version was released compiled for 2.00 and 
2.01 (or I'm wrong?).
That's all, and is just to add some information to the detection to take a 
better desition. 
Additionally stub-less COFF files can be detected by the library version. And 
very mixed things can be only created by people using alphas or similar stuff 
that normally knows what happends without the need of any kind of verify 
program.
