  /*
     OP: The point here is: When was %h dropped? and WHY?

     mha: It wasn't.  See above.

     OP: USING %lX with 2.953 seems to cause DJGPP to cause EXTRANEOUS
     GARBAGE to be output to the screen, and get this: from *OTHER*
     parts of the program !!!!

     mha: You just never bothered to read the beginner's information on
     using printf specifiers. */
