I added support for the /proc/self/exe method a few months ago, but only 
for Cygwin.  I didn't switch Linux to using it because I didn't want to 
break something that I assumed was working.

All that's really required is a #define change, but the attached patch 
also uses /proc/self/exe instead of /proc/$$/exe.  (/me slaps forehead.)
