Sorry, I need more help here. I read the page and I see no answer to the
question:

Does clisp need to know whether LC_MESSAGES is supported by the system,
or is a fake one defined by libintl or gnulib.

Please remember that I am an "English-only bigot" who believes that all
i18n/l12n efforts are a waste of time :-) so I know very little about
gettext et al and I wish I knew even less.

CLISP includes libintl.h only if ENABLE_NLS is defined (i.e., when
gettext is present).
It uses HAVE_LC_MESSAGES in spvw_ctype.d:init_ctype which is called
unconditionally in spvw.d.
I.e., on platforms without gettext where LC_MESSAGES is not defined
init_ctype is still called and its call

  setlocale(LC_MESSAGES,"");

must be guarded by either "#if HAVE_LC_MESSAGES" or "#ifdef LC_MESSAGES".
