I am trying to implement the function statfs(), which is the UNIX
function used for determining how big your file system is and how much
room is left.

To do this, I was going to use interrupt 0x21 with AH = 0x36, which is
the DOS call that returns this kind of information.  Unfortunately,
go32 doesn't support this particular interrupt/AH combination.

The following context diff should fix the problem (in DJGPP 1.07), but
I can't test it because I don't have Turbo C++.

I would be most grateful if someone would apply this diff, remake
go32.exe, and mail a copy of it to me.  Then I could test my statfs()
function, and if it works give it to DJ to include in DJGPP.
