95686b169e Moved actual computation of DOS 3.3 header to linker configurations: 
- This will allow for different "formulas".
- This brings things together in one place.

ffc06fcea3 Apple GEOS reserves beside the main app area at $4000-$C000 a secondary app area at $0C00-$2000. While it was an elegant idea to use that secondary area for overlays at the end of the day those 5 kB are just too small. So now overlays go at the end of the main area (as with GEOS 64/128). 
However the stack (usually 1 kB) can be securely placed in the secondary area without effort from the side of the developer. The rest of the secondary area (usually 4 kB) is made available to the developer as (uninitialized) 'EXTBSS'.

65fe2ad0d3 Add a new module that works around a bug in the Microsoft version of stat. The 
function is buggy since the first version of windows that supports something
else than FAT, and instead of fixing the problem, Microsoft has declared it
"works as designed". The problem has made it into .NET and is also visible in
the standard windows file explorer (modification times of untouched files will
change when entering or leaving DST).
Please note that the new FileStat function returns incorrect times for files
on FAT file systems. This is because I have currently no idea on how to
identify the file system for a given file. However, it should be correct in
quite some more cases than stat().
