  Section 11.9 of the Gnat 3.15p User Guide talks about this.  They
suggest you change the structure of the program, but do say this may
be impractical.  Their second suggestion is to use the "-gnatE"
option so "The behavior is then exactly as specified in the Ada 95
Reference Manual."  Claw assumes Ada 95 behavior.
  Gnat used to follow the Ada rules on this, but they decided to change
the default behavior to something else with Gnat 3.15p, thus breaking the
Claw installation instructions.  The Claw instructions for Gnat users
clearly need to be changed to reflect this.  BTW, IMHO you should also use
-gnato to get Ada behavior on overflow.  Failing to do this will not
generate any compile errors, any errors would occur at runtime.
