Fixed bug #193 The attached patch is mostly cosmetic: Currently, we always add both -framework OpenGL and -framework AGL for Mac OS X command line builds. However, the former is only used for the Cocoa video driver, and the latter only for the Carbon video driver (as far as I can tell, at least). Hence the attached patch modifies configure.in so that each only gets added to the list of frameworks if the corresponding video driver is enabled.

CLASS="STRUCTNAME"

CLASS="STRUCTFIELD"
><I

></TT
>) coordinates are reported along with the current button states (<TT
CLASS="STRUCTFIELD"
><I
>state</I
></TT

CLASS="LITERAL"
>SDL_BUTTON</TT
> macro (see <A
HREF="sdlgetmousestate.html"

CLASS="FUNCTION"
>SDL_GetMouseState</TT

HREF="sdlwmgrabinput.html"
><TT
CLASS="FUNCTION"
>SDL_WM_GrabInput</TT
>(SDL_GRAB_ON)</A
>), then the mouse will give relative motion events even when the cursor reaches the edge fo the screen. This is currently only implemented on Windows and Linux/Unix-a-likes.</P
