Hmmm. That also worked for me.

I don't either, but I don't really care. I'm quite accustomed to the 
overwhelming majority of systems exhibiting what I consider grossly 
unacceptable side effects and temporal dependencies ("We won't tell you 
how they're related, but you have to do X first, then Y, then Z...") So 
apparently autoconf/automake are merely another such system. Thanks for 
tracking the problem down for me!

By the way, at least on Mac OS X, I also had to edit rcs_file.cc to add:

#include "config.h"

#if HAVE_FCNTL_H
#include <fcntl.h>
#endif

to get open() and O_RDONLY.
