This message is completely off-topic in this newsgroup. Further, what you 
describe has already been tried by a whole bunch of hapless people and 
rejected. If you want to use EQUAL for ==, then you should not be using C.
(See C faq 10.2 at http://www.faqs.org/faqs/C-faq/faq/).

the point is, if you want a logical operation, use the logical operator. 
OTOH, if you want a bitwise operation, use the bitwise operator.
