I don't know what the expected output of AM_GNU_GETTEXT is.  Should we expect
it to set INCINTL or CPPFLAGS?

In any case, INCINTL is reset to an empty value in intl/configure.ac, and CPPFLAGS
is used not fowarded to config.intl, so there's no way right now the preprocessor
flags found by AM_GNU_GETTEXT can make their way to config.intl.  It can be done
by assigning CPPFLAGS to INCINTL, like this:

With this, I am able to get the build to go further.  I don't know if this is
just papering over the real problem or if it would be a valid solution (of
course not as-is, since it doesn't consider the USE_INCLUDED_LIBINTL=yes case).
But in a sense if AM_GNU_GETTEXT sets CPPFLAGS to -I/usr/local/include, it's
because it found out that this flag was needed in order to use libintl.  And
the INCINTL value in config.intl should contain the preprocessor flags needed
to get libintl working.  So it might make sense to do it...
