    Power Windows V1.3, wonderful program that it is, makes several 
    incorrect type declarations within the structures it writes for
    compilation under Manx.
    
          BorderVectors is defined as USHORT and should be SHORT
          
          By default, the text pointer in an IntuiText structure
          is defined as BYTE * and should be UBYTE *

          The same is also true of the text pointer to the window 
          name in a NewWindow structure.

    So far these are the only noted problems, though there may be more.
    (I haven't generated anything extremely complicated with Power 
    Windows yet.)  Left untreated, these incorrect declarations, cause 
    great aggravation in the form of a humongous compiler warning list.

    Crude, but effective, this program reads the source code file
    generated by Power Windows; through "casting" corrects the 
    troublesome buggers and writes out a corrected file with a .pwfix
    suffix in the same directory.
   
    If you plan on modifying the Power Windows source code (putting 
    things on the same line, etc.), I suggest you do so after running
    PWfix on it, as its relies heavily on the line structure of the 
    code to accomplish its goals.

    If you find other problems or modify this code substantially, please
    drop a hardcopy of your new source code listing in the mail to:
