Those are the times to compile the source code. The execution times
were much closer (0.2 sec gcc vs. 0.5 sec gnat, dumping the output).
If you meant the compiler I/O, the sizes of the source files were
around 45kb for C and 82 kb for Ada. So if the I/O is the limiting
factor, I would expect gnat to be slower by only a factor of 2, not
10, provided that the parsing routines have similar efficiency.
The bottleneck is not in the checkings, since the use of -gnatp does
not modify the times.
I don't pretend this is a good test, after all I did it in 10 minutes
yesterday night.
