The following is the solution that comes to mind for me.  My other idea was
creating a static char* or a static function with the char* inside it, in
the hopes it would be discarded as unused, but gcc doesn't seem to do that.

Seems to me that compared to this, rewriting those docstrings that are
victim of preprocessor definitions already is certainly better for
readability of the docstrings in the source code...
