  Modified files:
    usr.bin/m4           Makefile eval.c expr.c extern.h gnum4.c 
                         look.c m4.1 main.c mdef.h misc.c 
                         pathnames.h stdd.h trace.c 
  Added files:
    usr.bin/m4/TEST      math.m4 
  Log:
  Sync with FreeBSD.  Notable changes:
  
  Kill extraneous whitespace.
  
  Flush streams before calling system() so that the output appears in the
  right place in the output stream when redirected to a file (when full
  buffering is enabled).
  
  Store a pointer to "null" in struct ndblock's defn member instead of a
  duplicate allocated on the heap; the address defn points to is significant,
  and is checked against the address of "null" in certain conditionals.
  
  Fix m4 to properly handle bitwise operators &, ^, and |. Fix operator
  precedence. Add short-circuit evaluation.
  
  Respect locale settings from the environment.
  
  Add a new m4 script to test the functionality of math operators in eval().
