Yes, I considered this - but only theoretical ;-) because I can't do this.
Anyway I heard that good compilers produce much better assembler code than
humans (?).

I use GNAT. I am working on a AMD Athlon and Win98.

Well, _any_ difference? Hey, this is unbelievable! The difference between
the program compiled with
standard options and the program compiled with -gnatp and -O3 is terrific.
The acceleration is about 70%! The new compilation needs only about 1/4 of
time the old one needed. I can't believe it.
The new program is about 1/5 smaller than the old one.

I thank you very much. I never thought that might make such a great
difference. I guess I will never use standard options of compilers any more
in future :-)
