MFC r280357: Build expr with -fwrapv, since it relies on signed integer wrapping having defined behavior. Reported by: rodrigc 2015-04-06 14:45:40 +00:00			`# 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. Announced on: toolchain@ 2013-04-19 19:45:00 +00:00			`NO_WMISSING_VARIABLE_DECLARATIONS=`
