Simplified using new yacc rules and by not generating y.tab.h. 1998-05-04 14:41:16 -04:00			`PROG= expr`

Build expr with -fwrapv, since it relies on signed integer wrapping having defined behavior. Reported by: rodrigc MFC after: 3 days 2015-03-22 18:40:32 -04:00			`# expr relies on signed integer wrapping`
			`CFLAGS+= -fwrapv`

Add the Clang specific -Wmissing-variable-declarations to WARNS=6. This compiler flag enforces that that people either mark variables static or use an external declarations for the variable, similar to how -Wmissing-prototypes works for functions. Due to the fact that Yacc/Lex generate code that cannot trivially be changed to not warn because of this (lots of yy* variables), add a NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this specific compiler warning.
