Records what actually compiles now - d4 and 30 of 33 standalone demo
programs - and how to collect prototypes for a multi-module program,
which is the one part of the build that is not obvious: fglproto takes
the .dat files rather than the .4gl, and they all have to go in
together or a cross-module call cannot be typed.
Replaces the SQL known-gap, which is done, with the ORDER BY report
path, which is not. Adds the four things the probes caught since the
last update to the list of mistakes they caught - including the
comparison-returns-INTEGER one, which compiled everywhere and was still
wrong.
