There is a difference in 64-bit vs 32-bit, and it is more than just the problems of no vm86() call so hardware interrupts are not properly handled (aside - is that fixed now/soon?). I found I could use the MS C6.0 compiler and the 'PWB' (programmers workbench) for compiling the DOSD software OK under 32-bit Linux, but not under 64-bit as the dosemu instance would simple exit, as if exitemu was called (but it wasn’t). While I know MS had a lot of dubious and undocumented calls, the difference I saw was definitely a memory issue, and maybe related to the various XMS/EMS extenders that were needed at one time, when 640k was no longer enough for everyone...
