   In the mid-1980s, Niklaus Wirth said that his Modula2 compiler (being   
   able to compile itself) had about 5000 lines of code, while typical   
   ADA compilers had about 50000 lines of code. Just for comparison.   
   [I suspect that Fortran H did much more sophisticated flow analysis and   
   optimizaton than any Modula compiler.  Just figuring out the loops and   
   dealing with GOTO statements is a challenge. -John]
