You need to use {$apptype gui} or use the -WG parameter. For the
compiler it is not known if the application needs a console or not.
If you use -WG, IsConsole should be false. Correct?

Digging I found that IsConsole is set in two functions in
wprt0.as:
_mainCRTStartup sets to true and _WinMainCRTStartup sets to False,
this
cause a wrong setup of standard Output that DebugLn (lclprocs.pas)
use to
emit debug messages.
It seems that this functions are 'used' in the linker script, for
example
ld .--verbose shows that by default a ENTRY(_mainCRTStartup) it's
used. I
looked into the generated lazarus link.res file and didn't find a
ENTRY
section so I guess it uses the default and that's why even when
lazarus is
a gui app, it's linked as a console app.
To demostrate this I modified the link.res script to inculde
ENTRY(_WinMainCRTStartup) section and then linked, the resulting
lazarus.exe file now behaves as a gui app and won't crash at
start.
It seems that WriteResponseFile lacks the code to add the ENTRY
section to
the link.res script but I don't know if it's supposed to be there
or
should it be in another stage, any comments?

Lazarus is already compiled with -WG
