be damned if I understand how configure finds and picks a cpp(1), and

its pick actually exists, to error out a thousand lines later.
I happened to come across <http://gnats.netbsd.org/53686>;, where people
dealt with a similar problem for pdksh.
The resulting patch to configure
<http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/editors/xemacs/patches/patch-c...
makes sure that preprocessor warnings from ambitious security settings
do not interfere with finding a working cpp(1).
This should go into configure.in, but what really needs to be amended is
the autoconf "AC_PROG_CPP" macro (which is also the source of the crufty
fallback "/lib/cpp").
I tried adapting various compiler options for the build, but it didn't
make a difference for the pdump SIGSEV.
Cheerio,
