[configure]: Warn of buggy Ghostscript versions.
* m4/groff.m4 (GROFF_GHOSTSCRIPT_VERSION_CHECK): Add new autoconf macro
to check if Ghostscript version. Versions 9.00 <= x < 9.54 suffer
from a rendering glitch that affects the AT&T troff (and groff)
special character \(lh; see
<https://bugs.ghostscript.com/show_bug.cgi?id=703187>. Store the
result of the check.
(GROFF_GHOSTSCRIPT_VERSION_NOTICE): Add new macro to report the
problem detected by GROFF_GHOSTSCRIPT_VERSION_CHECK to the user.
* configure.ac: Call the macros in appropriate places.
Fixes <https://savannah.gnu.org/bugs/index.php?59531>.
I did not name GROFF_GHOSTSCRIPT_VERSION_NOTICE consistently with other
groff autoconf macros of similar purpose; I find the existing names,
ending in "_CHECK", confusing because these don't perform checks except
in a trivial sense (effectively of a single Boolean variable). Instead
they are wrappers around a lengthy parameter to AC_MSG_NOTICE.
By contrast, GROFF_GHOSTSCRIPT_VERSION_CHECK does the actual ugly
business of calling `gs -v`, munging the resulting string, and
comparison. (I tried AX_COMPARE_VERSION but couldn't get it to work,
and in any case the Ghostscript versioning scheme is simple and sane.)
I'm open to feedback on writing more idiomatic autoconf macros.
