would it be possible to make the console version of fasm.exe use the fasmw.ini file?

It would be possible, though doesn't make much sense for me - note that this file has the same name as executable, with .ini extension instead of .exe; if you rename FASMW.EXE to ABC.EXE, it will use ABC.INI.

I have some windows code I would like to compile but uses the
%fasminc% variable, but doesn't work with fasm console (even after renaming the fasmw.ini to fasm.ini )

As you use the console version from command line, there's not much problem with setting environment variable there. Also you can make FASM.BAT or FASM.CMD which will set the variable and call the executable.

All right, got it working, thanks!
