  * mkstr - create a string error message file by massaging C source
  *
  * Bill Joy UCB August 1977
  *
  * Modified March 1978 to hash old messages to be able to recompile
  * without addding messages to the message file (usually)
  *
  * Based on an earlier program conceived by Bill Joy and Chuck Haley
  *
  * Program to create a string error message file
  * from a group of C programs.  Arguments are the name
  * of the file where the strings are to be placed, the
  * prefix of the new files where the processed source text
  * is to be placed, and the files to be processed.
  *
  * The program looks for 'error("' in the source stream.
  * Whenever it finds this, the following characters from the '"'
  * to a '"' are replaced by 'seekpt' where seekpt is a
  * pointer into the error message file.
  * If the '(' is not immediately followed by a '"' no change occurs.
  *
  * The optional '-' causes strings to be added at the end of the
  * existing error message file for recompilation of single routines.
