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'.

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().
