That bignumbers webpage is out of date. It is of 2003, and by Jerome
Delcourt. GMP is of http://www.swox.com/gmp/.

I have fuller GMP bindings (that lack all types of arbitrary viral
licences [anyone got a website categorizing the different types that
neutralise threats?]):

  http://terratope.tigris.org/source/browse/terratope/trunk/cy/ (GMP)

I looked at the Debian shootout page

   http://shootout.alioth.debian.org/debian/ada.php
   "Ada 95 GNAT" (Debian Sempron)

and it seems all untrue. For example, the main table in the centre is
titled:

   "How many times faster or smaller are the Ada 95 GNAT programs than
          the corresponding C gcc programs?

   "GNAT x times better
   - gcc x times better"

So most of the numbers are nearly all negative.

Thus it is probable that the creator of the website wishes to present
himself/herself as observing that GNAT executables
   finish running before they start.

That gives a narrow to print out backtraces...

For a clarification, the "ada.php" webpage shows an image that
contains images of horizontal bars.

Of them I note:

  * none are labelled. However the first word on the webpage is 
   "Debian" (rather than, eg., "Linux").

  * Something is labelled in the plot: and that is the horizontal
   axis.  It has two labels that are not clarified:

      (a) "GNAT better" (on the right)
      (b) "gcc better" (on the left).

So what is the "-" symbol mean, in the text "- gcc times better".

Special reasoning skills are possibly needed to prevent modifying
scripts so that --sysroot is added to ld linker operations and then
the GNAT compiler is actually built under the FreeBSD emulator.
FreeBSD seems to be getting faster, and maybe the buildword is
less likely to crash too.

Here is the competing Windows "shootout" webpage:
