IMHO, such ``solutions'' are not a good idea: they tend to sweep
problems under the carpet rather than really solve them.  A ``real''
solution would mean that the reason for such a problem is well
understood and acted upon.  For example, if this is a bug in FreeDOS,
a proper description should be added to the DJGPP FAQ list and the
library docs, so that others won't need to fight those same problems;
if it's a bug in the DJGPP library, it should be corrected; etc.

Is it possible that FreeDOS has some long-file-name emulation in it?
If so, please try to turn it off, and see if that helps.  The only
real difference between findfirst and _dos_findfirst is that the
latter doesn't try to use the long file-name API, even if it is
present.  Otherwise, the two functions do the same.

Again, please try to run this program with the long-file-name module
disabled.
