Re: Problems building testgtk

[Larry McQueary <mcqueary attbi com>]

Well, I'm not sure about plain old C, but ANSI C++ considers any const 
to be private to its translation unit.  I can only intuit that somehow 
GCC is doing the same in this instance, even though it's being called as 
gcc and not g++.

I agree that removing the const from the declaration clears the problem. 
I suppose I should have enumerated that potential solution as well, 
although I don't care for it from a purist perspective :-)  

I'll try to figure out how to fix this the right way once I can 
duplicate this in a simple example (which I can't so far).

Thanks,
Larry
