[TUHS] Building the two-pass Portable C Compiler

Also look at ucb/mkstr.c and man/man1/mkstr.1 in the 2.11BSD.

  * 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.

So you may be able to use mkstr to generate it.

Some examples in 2.11BSD also include kermit, sendmail, and news.

I believe that the code uses mkstr to build a single file of all the 
error strings and builds replacement code that excludes the error 
strings but uses offset number instead.
