OK, just to be into this benchmarck craze, I did a few tests w/ gcc
and family.
These are the results, using GCC 2.95 (mingw) and gnat 3.13p on a PII
666MHz w/ NT 4.0:

GNAT    11.0 sec
g77      4.0
gcc      1.4
g++      3.3
obj-c    2.6  (writing a "cout" class)
gcc 2.8  1.0  (gnat gcc)
gpc 2.8  1.1

The programs are 1000 loops like:

for i in 1..100 loop
  ada.text_io.put_line( Integer'Image(i) );
end loop;
for i in 1..100 loop
  ada.text_io.put_line( Integer'Image(i) );
end loop;
....

or

for (int i=0; i<100; ++i)
  cout << i << endl;

and so on...
OK, GNAT is slower... and so? Anybody cares?
