[M3devel] Windows

[Tony Hosking]

With the current native Windows backend (m3back) blindly assuming  
(without even checking!) that all integer operations are 32-bit, I  
wonder if anyone out there has the expertise, time, or inclination to  
smarten it up to handle both 32-bit and 64-bit ops.  It should not be  
*too* hard, but I don't have the time for it now, though I would be  
happy to answer any questions that arise.  Unfortunately, this  
reveals that Windows support is withering on the vine, in spite of  
Jay's excellent recent work.  As of now, this means that Windows can  
only build CVS sources with the tag devel_LONGINT_start.  Bridging  
the gap will require smartening up m3back or using the gcc-based  
backend.
