This is a very good solution, used by other packages as well.  (See the 
TeX-related programs, for one example.)  However, it has a small but nasty 
pitfall: argv[0] is always the short 8+3 path, even if you run on Windows 
9X.  This might not be a problem at all if you only need to access a file 
using that path, but if you use argv[0] to compare it to some other file 
name, you might think they aren't the same if the other file name is long.

I don't know if this is a problem in the current context.  If it is, a 
call to _truename should solve it, but _truename might return remote files 
in the UNC-style \\SERVER\SHARE\FOO form, and you then need to convert it 
to the normal d:/foo/bar form.  (Yes, the DJGPP port of TeX does all 
that.)
