Yes, I had a look at that, too , when I first saw it. We can get rid
of the warnings by sticking `volatile' before the declarations if we care.

Any compiler out there that does not suppport volatile? YACC - Yet Another
Configure Check.

Ah, I see.  It's warning you which variables have been given register
storage allocation by the compiler, and which therefore won't be unwound
properly when longjmp() takes you back up the stack to the setjmp() spot.
As long as none of those are referenced in the `if (setjmp(...)) { ... }'
blocks (which appears to be true), everything should be OK.

These have always been there and I've never been able to understand what
it's talking about with those particular variables.

        Both machines have the zsh{rc,env} from the RedHat zsh-3.0.7-4 
RPM.  But nothing really out of the ordinary is set (at least as far
as I can see).

Is there anything in /etc/zshenv or /etc/zshrc that's the same on both
machines?  "make check" has the problem that it's vulnerable to being
messed with by the global rcfiles, and completion is the most exposed.

        As a followup to my report of failures, I did get 07cond.ztst
failing and the directory in question was mounted NFS.

Got compiler warnings:

zftp.c: In function `zfgetline':
zftp.c:730: warning: variable `added' might be clobbered by `longjmp' or `vfork'
zftp.c:732: warning: variable `pcur' might be clobbered by `longjmp' or `vfork'

"make check" fails 07cond.ztst if and only if the build directory is on an
NFS filesystem (all tests succeed if the build is local).
