What did you do when you saw such a usage message?  If you typed
`w3m' in the terminal emulator, not in Emacs, it's normal.  Give
*URL or filename* as an argument, and w3m will work as expected.
If you typed `M-x w3m RET' in Emacs, I have no idea.

BTW, emacs-w3m 1.4.4 is rather old.  Though it's the latest
released version of emacs-w3m.  Personally I recommend using the
CVS version of emacs-w3m, in which many bug fixes and improvements
have been done.  It is available as:

http://cvs.namazu.org/emacs-w3m.tar.gz

I heard setting the environment variable GC_NPROCS to 1 is necessary
only for using GC 7.0 on MacOSX.  Is it still necessary and effective?
