Update to 0.4.

release 0.4 (20130713)
   - Fix stupid build problem introduced in 0.3.1.
   - Accept and ignore -m32, which imake issues willy-nilly on a bunch
     of platforms. I thought this had already been done, but apparently
     not.
   - Don't use the <err.h> functions. There are still people out there
     using legacy systems missing them.
   - Sort out some more issues pertaining to handling quoted strings.
   - Add some more tests.
