  The original definition of CTRL does not work in ANSI compilers,
because parameters are not substituted in strings and character
constants. I made the following redefinition:

        #define CTRL(c) (#c[0] & 037)

  What should really be done is to change all the calls to use a
character argument (ie. CNTL('x')), but this is quick and dirty. Does
not generate the best code, though.
