Compiling a PM sample with GCC (2023)

[Martin Iturbide]

Thanks Alex, Mentore.

Now it compiles without warning. I had included the latest changes on the github.

If you have any suggestion about FatBits, I will appreciate it. I didn't think it was going to be able to compile it since it came from 1990, but it compiled with some changes, sadly the magnifier screen does not refresh when the mouse moves.
