Alignment issue on x86_64?

No, I'm building with those CFLAGS : -g -ggdb -Wall -save-temps 
-fno-strict-aliasing

You're absolutely right, CARD32 is defined as an "unsigned long" on x86 
but as an "unsigned int" on x86_64. Changing this does not however 
change anything in how the Xlib call done just before behaves.

Doesn't change anything. No additional warnings nor any change in behavior.
