gettext 0.11.2: setlocale() ?

[Paul D. Smith]

I'm testing my new installation of gettext on various platforms; I'm
using the "external" method for Gettext support.  On Linux, where
libintl etc. exist, everything works great.

On Solaris, where it doesn't, I get a compile error at the line:

  setlocale (LC_ALL, "");

due to LC_ALL not being defined (and, presumably if I fix that, for
setlocale() not being defined.

I can see a number of ways to fix this: add it as an empty macro to
gettext.h; test the HAVE_SETLOCALE config.h variable which the
gettext.m4 macros already set up for us via configure, and don't compile
that line if it's not set; test HAVE_LOCALE_H and make setlocale() a
macro expanding to empty (this is what diffutils does).

However, what is the _right_ way to fix this?

Nothing in the gettext manual discusses this; the examples just use
setlocale() as an initialization along with other functions which are
handled by gettext.h.
