MPLAB and wine

The MPLAB version I have apparently doesn't run on 64 bit linux.

The error message:

  winevdm: unable to exec 'D:\tom\.wine\drive_c\MPLAB\MPASM.EXE': DOS memory range unavailable

Goes away after this:

  sudo sysctl -w vm.mmap_min_addr=0

Now the message (on 64bit) is:

  wine: Cannot start DOS application "D:\\tom\\.wine\\drive_c\\MPLAB\\MPASM.EXE"
        because vm86 mode is not supported on this platform.


According to [3]:

Ok, full emulation then..

Hmm.. I also tried the pic30 chain at [4].  I did find some compiled
debs that work on 32bit[5] but the compilation of [4] requires deps I
don't have.  Too much hassle.
