Was there some way to detect whether code is compiled as Windows console

to differentiate them?
AllocConsole fails for a console subsystem: "A process can be associated
with only one console, so the AllocConsole function fails if the calling
process already has a console."

So that Windows GUI version would force the separate console window, but
in the Windows console version they would be no-ops (like is the case on
every other platform)?
But you don't have to change anything in Hatari (besides of course the
gcc option from "-mwindows" to "-mconsole") to build a console version.
The return value of AllocConsole is not checked anyway in Hatari's
Win_OpenInternal. For a console version, AllocConsole silently fails and
no *new* console window is opened. The existing console is used, as
desired.
