Sigh.... I reported this quite a long time ago [PR bin/774].  I think
part of the problem is that the fdesc filesystem makes /dev/stdin and
friends symbolic links to /dev/fd/_number_.  Following is a very old,
and perhaps non-working, patch to compress to get it to work again.  I
discovered this in the first place, when I built X11R6.  It failed to
build the fonts.  As an alternative one can replace the above line
with:

		compress < gated_dump | cat > gated.dump.Z
