Oops. Yep. Left to right, so its the same as
((print_verbose_messages & VB_MEDIA) & VB_EXTRA)
The first expression is either 0 or 0x00800000.
Either of these ANDed with 0x40000000 is 0!
I'm still lost about this form, though:
(print_verbose_messages & (VB_MEDIA+VB_EXTRA))
0x00800000 + 0x40000000 should be 0x40800000,
no matter how the compiler slices and dices it?
I originally started using the A+B form because
it makes it clearer in a VERBOSE call that both
values are required.
