AFAIK Nicolas built the Windows version (using Linux cross-compiler for
Hatari Windows binaries).


I found an earlier mail about the Windows build with a comment on similar 
issue:

opencon.c states:
"The SDL library redirects the stdio normally to the files stdout.txt and
  stderr.txt. But with this redirection, the debugger of Hatari does not
  work anymore.  So we simply open a new console when the debug mode has
  been enabled, and we redirect the stdio again - this time to our new
  console."

So, now I wonder whether these comments are specific to MS C/C++ compiler
and would "--subsystem console" work also with that...?
