  I didn't test it out before:
it does work on my system, but is it
sure it will compile and link correctly on
all C compilers used for GDB?

  There is apparently no trace of your_gdb_wchar_t_is_bogus
in my charset.o object file once it is made external.

  Could someone confirm that this will also compile
on other C compiler used without creating link failures?

I am perfectly willing to change this but it seemed
to me to rely on some "obscure C compiler feature"
(don't forget that I learned C to be able to support pascal
language in GDB...).
