Regarding this:

Do you know if it'd solve the problem to make the prerequisite tests

Yes, it would.

I really hope so, because using cache variable names
from other tests makes the code very fragile -- I've been burned by
that too many times.  Even using cache variables defined in the same
file has been known to throw me :-)

I do see why that prerequisite-testing is conditional,
and agree in principle with the general goal.

I should hope so. Doesn't the "jm_" prefix on "jm_FUNC_LSTAT" mean you wrote the macro in the first place? :)

However, it'd be much better if macros like AC_FUNC_LSTAT and
AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK took optional `run-if-true'
and `run-if-false' arguments.  Then we wouldn't need to rely on
fragile cache variable names.

I've Cc'd the autoconf discussion list.
If no one objects, I'll change the stat/lstat-related AC_
macros as I've suggested.

Did you have an opinion about my tweaks to stat.c?
