I suspect for the mainstream of Windows C++ suites (e.g. Visual C++,
Borland), the guide is dated and you could probably delete large chunks
of this guide but only if you knew that was your entire porting range. But
mozilla's porting range is huge and a lot of the rules seem to apply
because of HP and SCO compilers - which I had expected to be fairly
common targets...

This sort of thing isn't limited to C++ though, just now my porting range
includes Green Hills AdaMULTI v2 for PowerPC, which doesn't cope
with 64-bit integers as well as GNAT does. Can't wait for v3 to drop on
my doorstep!..

Also, some compilers don't produce very efficient (in size) code for

package body X is
  ...
  Y : Y_Type := (others => (...));
  ...
end X;

and it is usually necessary to change this to

package body X is
  ...
  Y : Y_Type;
  ...
  procedure Initialise is
  begin
    for Index in Y'Range loop
      Y(Index) := (...);
    end loop;
  end Initialise;
end X;

one could say they were 'irrational' about it ;-)

anyone else got any porting tips - maybe we could start a FAQ for these
sort of things?..
