Details:

The header "gnumake.h" has a definition for the type "gmk_floc", but there's
no obvious/apparent way to make use of it.

In my code I have a declaration of the form:

__attribute__((weak))
const gmk_floc* reading_file;

... I use for generating errors with file:line pairs and getting the current
makefile.

I would like to see something a little more concrete in the API, whether it's
"reading_file" that gets exposed directly or a function we can call & pass a
pointer to a gmk_floc instance to be populated.
