I'd thought, thet gcc maybe tries to determine the filelength on=20 opening
and stores it for possible later access - and that's where it fails.

From DOS-programming, I remember there were some interrupts with=20 parameters.

Shouldn't it be possible to just change some parameters to handle big=20 files
correctly ? Why is it so difficult ?
