pure-gen generates duplicate stubs

[GoogleCodeExporter]

Duplicate C prototypes are perfectly valid C, but pure-gen generates multiple 
stubs with the same name as a result, which is not valid C.  On my system, 
unless you mess around too much with #defines, gl.h and glext.h both define the 
gl-1.3 prototypes.

pure-gen should probably intelligently choose the best available prototype if 
more than one exists (e.g. it might even be a dummy k&r-style duplicate).  
However, simply removing duplicates (and tightening the NV inclusion regex) 
allows me to generate/compile pure-gl.  I've attached a patch which removes 
duplicates (probably sub-optimally, as I don't really know pure -- it's just a 
suggestion, anyway).

Do you have a test case?

I have attached a change to run-tests which verifies the operation of the fix.  
I should have mentioned that the problem is with -fc, as used by pure-gl.  Note 
that without the fix, two identical Pure_rand() functions are generated.

Committed, thanks for the patches! I committed a slightly modified version 
which at least spits out a warning if the prototypes are different. Please let 
me know if this works for you.
