Comment (by kgardas):

 Thanks for investigation. In its light, have you changed your attitude to
 my proposed patch? I'm afraid that if we're going to support several nm
 output formats, then either the code looks like you criticize or we need
 to employ some Haskell library for parsing which I'm not sure if it's not
 over-kill in this simple case. I'm curious how things work on MacOSX or
 *BSDs. IIRC On Windows we're using GNU tools and no other commercial UNIX
 besides Solaris looks supported...
