I have tested today latest changes on Windows 7 32 bit, Windows 7 64 bit, Ubuntu 10.04 32 bit without any issue.

No, since the image files (and other data) are only read in the 2 Zip files, in a case-insensitive mode. At this stage the operating system has no control anymore on names and their case-[in]sensitiveness...
What happens when you run the Linux executable that is shipped with the whole stuff ? - I mean: ./globe3d_demo_linux ?

Sure. And it uses the modularity ([Gl.]Name) instead of glNAme of the flat macro-assembler model. And also uses name overloading, like Vector instead of glVector3i, for instance.

Thanks for pointing that, I'll make the appropriate change!
