BTW, i found small bug:
When importing microsoft visual c++ project, it asks what compiler to use. I choose "microsoft visual c++ toolkit 2003" . Then it asks to "convert compiler/linker command line switches to GCC's switches , yes/no?" . I choose "no" . Then i open project->build options , and see that while in project settings itself, visual c++ toolkit is selected, in "default target" ,GCC is selected. It prevents things from compiling.
