   As far as I know, FreeDOS does not have LFN support.  I suspect the
difference between _dos_findfirst and findfirst goes deeper than just
LFN support -- They use different file control structures, which
indicates to me that there's probably something else going on.  I
should probably take a peek at the source code for these two functions.

I suppose I should also take a peek at the fopen source code to see
what's going on.  I think I'm also going to try compiling this same
snippet of code under Borland and see if I have the same problem.  This
should at least tell me whether it's a FreeDOS issue or a DJGPP issue.
