I don't think so.  On MSDOS, Perl closes stdaux and stdprn (FDs 3 and 4)
at startup, as there is no way to use them from Perl.  For some reason,
this causes serious issues with programs spawned from a DJGPP-built
Perl.
I suppose you could have a C program that opens a file and reports the
FD; then run that program from a Perl script.  If it reports '3' on
DJGPP,
the problem exists; if it reports '5' it doesn't.  I really don't think
it's worth it to test for this.
Additionally, the actual problem may be more fundamental, with Perl
merely tripping some library bug, in which case Perl may be changed
back,
rendering the test moot.
