Ok. I've just set up a writeable repository, and should be able to
commit. If not, I'll let you know.

Yes, we do need two macros. The helper macro (__TOSTRING__) can be named
something else, but it's needed to force parameter expansion. Otherwise,
TOSTRING(__LINE__) would have produced "__LINE__", not the stringified
value of __LINE__. This is straight from the K&R book...
However, I just looked, and this kind of macro seems to be defined already
in /usr/include/symcat.h (XSTRING). I'm not sure whether it's better to
use the pre-existing macro, or to to define our own (with a more intuitive
name, IMO). The macro is simple enough. Opinions?
