You are mistaken.

The only constraint is that you have to "#include <libcharset.h>" and need
to link with the library that has locale_charset() defined.  Does everybody
has that function in -lcharset, or a system you do not know have it in some
other library?

For example, Msysgit part defines HAVE_LIBCHARSET_H but it apparently does
not need -lcharset. It could be that the port is incomplete, but another
possibility is that perhaps the function is in part of libc and does not
even need -lcharset passed to the linker.

If you look at our Makefile, you see "On this platform foo() can be
obtained by linking with -lfoo, but on this other platform you need to
link with -lbar" gotchas around some libraries (e.g. ssl/crypto), and I am
wondering if this function has a similar issue.
