op precedence in C

[utzoo!decvax!wivax!linus!sch]

The question about statements like:
	if(x & a == b)
is not a difficulty with precedence in the C language.
The problem is that you are using & instead of &&.  Using logical instead of
bitwise AND in if() statements is something which must be bred out of
C programmmers.
