Wait a minute.  Are you saying that the problem is _only_ with GCC
compiled with DJGPP 2.04, and that 2.03-compiled GCC works?  I don't
think you said that before.

If you compile with v2.03 a simple program that calls 7A46, and then
run it with DOSLFN, does it also fail?

If so, this is certainly due to the use of 7A46, because in v2.03
`filelength' didn't call that function and `lfilelength' didn't exist
at all.

So I think we need to fix these 2 functions to work around this
problem.
