The difference between different compilers for the SAME language on the
SAME machine running the SAME operating system can vary by more than a
factor of five.  This makes it very difficult to get objective
measurements of the difference in speed a language makes (assuming 
all the languages being compared use the same execution technology:
all are compiled or all are interpreted).  The parse tree that is
generated by a C compiler and the one generated by a Modula-2 compiler
are extremely similar.  They can pretty much share the same code
generator.  In those systems where they do share the same code
generator, they produce very similar benchmark results.
