I would guess this is the same issue that prevented autoconf 2.52 and
higher to work under DJGPP.  If so, the culprit is perl.c, which closes
stdprn.  This causes programs run by perl to recycle fd 3, but the exit
code won't close (and flush) that fd properly because it thinks that it
is stdprn.  Simply not closing stdprn fixed this (and made autoconf 2.52
work.
