windres compatibility for wrc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



As discussed here:
  http://www.winehq.com/hypermail/wine-devel/2002/12/0168.html

I think we need to cleanup a bit the options to wrc, but I will
do that in a different patch, once this gets in.

BTW, with these changes, and mingwrap, putty gets to linking.

ChangeLog
  Make wrc command line compatible with windres.
