should we change "unknown" to $GID & $UID respectively ?
I guess it couldn't hurt, although I doubt it makes any difference in
practice.
if test $am_uid = "unknown"; then
Don't we usually avoid quoting constant strings? I.e.:
if test "$am_uid" = unknown; then
AC_MSG_WARN([ancient id detected; assuming current UID is ok, but
dist-ustar might not work])
"Might"? Either it works or it doesn't? Anyway, who ever uses ustar?
Never seen it.
Anyway, seems like such a warning "might" be useful when producing an
archive with automake (running make dist), but not when running
configure. When merely doing "./configure && make", ustar is irrelevant.
Anyway #2, I think the chances of someone wanting to produce a ustar
archive on a system with old id is zero.
Thus I suggest just fixing the syntax stuff and letting it go at that.
the point of the checks isn't just to annoy the user.
No :)? That's what it seems like. Helpful to the package developer;
annoyance to the configure user. -k
