There are two flavours of debugging information (Ada debugging and
CodeView - see the checkboxes on the link tab) optionally included in the
executables in *non-loadable* segments.  The use of each of these
significantly affects the size of "hello.exe" as the following table
indicates:

				   Ada debug
				Y		N
Codeview debug	Y	732104	331712
			N	732032	84480

Note that it is possible to remove debugging information from an
executable using the command "cvpack /strip".  The true memory footprint
is always most accurately determined from the link map.

In future versions it will be possible to link to the runtime in a DLL;
this further reduces the size of "hello.world" to around 10k without debug
(like MSVC).
