Actually, it's possible to make .COM programs with GCC but for that we also
need NASM plus some code to get into PMode. Basic problems are:
1. DOS/Windows treats .COM program as 16-bit real-mode
2. .COM file size is limited to 64KB
So, in general, it's not worth to mess with those things. Though I used this
for my LFBemulator.
