I get it ! There is the second copy of Qt library, but with GL extension 
compiled in. Is it true ? It isn't very clever, I think, because usually both 
librares have to be in memory.  If I put QTLIB before QGLLIB then the linker 
will catch Qt symbols from the first Qt lib, but it will not find any QGL... 
symbols there, so it will search further until it'll find them in the second 
lib.  It should even work if the both libraries have the same version, but 
maybe I'm wrong. If i put QGLLIB before QTLIB then it takes all symbols from 
the same library, but still - it will be formally linked to the two Qt 
libraries.  Am I right ?

Of course, if you want. I can give you the access to the website or you can 
just send me corrected files.
