[M3devel] upgrade fails with compilation error in m3quake

[Rodney M. Bates]

It looks like a bootstrap barrier.  My installed compiler does not complain.
The first argument has type LONGCARD, declared at m3-libs/libm3/src/os/Common/File.i3:34
This was changed from CARDINAL in 2010, no doubt to handle big files on 32-bit systems.
The compiler was changed to allow this at similar time.

I made changes to the failing code in QScanner in June of 2014, but it would have had
the same failure even before.

I'm not sure of the easiest way to proceed.  Figuring out what the intermediate step
would be could be tedious.  You might consider just editing the type in File.i3
to CARDINAL temporarily, to build a compiler, then change it back and recompile with
that.  But then, there could possibly be other such problems.

But in general, we should have an upgrade procedure that anybody can use, starting with
the release compiler, and no such manual stuff.  I suppose trying to compile the
current libm3 before the current compiler is the source of the problem.  Can you easily
recompile the compiler with your old libraries?   We seem to have had some bootstrap
barriers that require doing the libraries before the compiler and others the other
way around, which makes having a general procedure problematic.

Any ideas, Jay?
