Finding where an executable was run from -- a proposal.

I'm already using the convention that library/data files belonging to a
program are located in a path relative to the name of the program. So I
strongly second this suggestion. Until this is adopted by the next C
standard, we'll need to have a library routine which does the job, based on
argv[0] and the PATH variable (despite of the possible problems - there's
no better way).
