But don't see how to tell whether the type is trivial in m4.  If the
user defines the C macro YYSTYPE, then the code must assume that the
type not trivial.  This is not something that m4 can do, as far as I
know.

I guess that I have to do the former.

Sorry, I don't see how to do it in M4.  (On the other hand, I don't
understand the M4 model yet, partly because I can't bootstrap.)

OK, done.

I currently get the following in my attempt to bootstrap:

Please use AM_GNU_GETTEXT([external]) in order to cause autoconfiguration
to look for an external libintl.

Please update po/Makevars so that it defines all the variables mentioned
in po/Makevars.template.
You can then remove po/Makevars.template.

Please run 'aclocal -I m4' to regenerate the aclocal.m4 file.
You need aclocal from GNU automake 1.5 (or newer) to do this.
Then run 'autoconf' to regenerate the configure file.

You will also need config.guess and config.sub, which you can get from
ftp://ftp.gnu.org/pub/gnu/config/.

You might also want to copy the convenience header file gettext.h
from the /opt/reb/share/gettext directory into your package.
It is a wrapper around <libintl.h> that implements the configure --disable-nls
option.
