gzip 1.3.6 does not build on Tandem NSK/OSS because it uses fchdir,
which does not exist on NSK/OSS. This was added in gzip 1.3.5. Is
there a replacement for this function (e.g. in gnulib)? Can its use be
removed/conditionalized?
I looked into this some more, and decided that since all gzip uses
is fdopendir, it's overkill for gzip to bring in all of the openat
module. Perhaps we should split out fdopendir into a separate
module? But that'd be a tricky business, and right now I'm trying
to get a stable gzip out the door. Besides, gzip should really
be using openat, as that is safer than the current approach.
For now I installed this patch to gzip. This way, gzip doesn't use
openat. It does use fdopendir if the underlying system has it,
though. This lets gzip be safer on modern platforms (glibc 2.4,
Solaris 10) but less safe on older ones. Since it's been less-safe
for a decade without anyone complaining, I guess that's good enough.
