Due to copyright restrictions, the scangen, fmq, and spim tools must be
obtained directly from the University of Wisconsin.  See the README file
in the root directory of the distribution.

Fmq and scangen are old Pascal programs, with keywords in upper case.
In September of 1995 I successfully re-built scangen with
 
    /usr/lang/pc -C -H -s -g -o scangen scangen.p
 
-C says do run-time subrange and array bounds checking
-H says do run-time pointer (heap) checking
-s says accept only "standard" Pascal.  Among other things, this maps all
    keywords and identifiers to lower case.
-g of course says generate dbx/gdb stabs.

Makescan and makeparse are somewhat newer Pascal programs.
All of this stuff should really be re-written in C++.
