How to cross-compile on cygwin?

[roelf01]

Hello,

I'm using a full installation of cygwin and need to cross compile for i368 unknown gnu linux.
I've tried a special cross-compiler i found,
But it doesn't want to use the /usr/include dir nor the standard lib dirs.
This resulting in a lot of linker errors.
I need it to be able to use ncurses.
It may not replace the g++ from cygwin (i still need it for testing and compiling programs for the pc itself).
And it must accept the -I and -L switch (my current cross-compiler doesn't, causing errors).

Any idea's?
I've heard you can pass a switch to g++ setting it to use that target,
Does anyone know about that?
