I may be missing something here, but what does the fact that Windows may
be running in a VM have to do with which compiler/runtime is used?
If anything, the Microsoft runtime is more likely to be installed on
Windows in any case...

If you're talking about running Windows Lazarus programs that use
libpq.dll etc under Wine, that could be a different story...

Anyway, the OP is awfully quiet. I wonder whether his problem has been
solved or if he just decided to go out and braai...
