In section 2.5.1.1, "Syntax," revised grammar to properly treat ! as a unary operator.

Changed from:

; multiple rules for cond-expr to represent different precedence of || and &&

; super-term and factor are intermediate rules and used only in this part of the grammar

cond-expr = expr

expr = super-term [wspace] *( "||" [wspace] super-term )

super-term = factor [wspace] *( "&&" [wspace] factor )

factor = ["!"] [wspace] "(" [wspace] factor [wspace] ")"

factor = term

Changed to:

; multiple rules for cond-expr to represent different precedence of || and &&

; super-term and factor are intermediate rules and used only in this part of the grammar

cond-expr = expr

expr = super-term [wspace] *( "||" [wspace] super-term )

super-term = factor [wspace] *( "&&" [wspace] factor )

factor = term

factor /= "(" [wspace] expr [wspace] ")"

factor /= "!" [wspace] factor
