Good, glad that I could help with my opinion :)

As documented in [1], not every possible code modification is suitable for
gnulib proper. In this case, in particular, I don't think that code
that returns the locale encoding _if_ setlocale (LC_CTYPE, "") had been
called, without really calling it, is a frequent enough use-case.
If I were you, I would start using the gnulib-tool option --local-dir
with a local modification of the 'localcharset' module, as documented in [1].
This means:
1) Hack your local copy of localcharset.c so that it not only defines
the locale_charset() function, but also an additional function
environ_locale_charset() that looks only at the environment variables.
2) Store this file in guile:
$ cp ludo-localcharset.c guile/gnulib-local/lib/localcharset.c
or if there are few changes just the differences:
$ diff -u gnulib/lib/localcharset.c ludo-localcharset.c \
> guile/gnulib-local/lib/localcharset.c.diff
3) Pass the option
--local-dir gnulib-local
to the gnulib-tool invocation in autogen.sh.
