Subject:   Portability: rename basename() to rc_basename(), since the former
 is   quite widespread, and has a variety of different definitions (none of  
 them, of course, static).   Portability: work around i386 GCC 2.7.2.3
 optimization bug triggered   by a (really quite simple) expression in
 history.c.
