CWARNFLAGS?=	-Wreturn-type -Wcomment -Wredundant-decls -Wimplicit \
		-Wnested-externs -Wstrict-prototypes -Wmissing-prototypes \
		-Wpointer-arith -Winline -Wuninitialized -Wformat \

# When working on removing warnings from code, the `-Werror' flag should be

Turned on -Wformat -fformat-extensions. -fformat-extensions requires a -current version of gcc. Without it, -Wformat would complain about all the nonstandard %[Dbrz] formats in the kernel. 1998-09-09 10:04:58 +00:00			`# $Id: bsd.kern.mk,v 1.9 1998/05/01 18:13:37 bde Exp $`
Oops, forgot to cvs add bsd.kern.mk. Centralized the definition of CWARNFLAGS into bsd.kern.mk. 1996-10-08 22:10:49 +00:00

Turned off -W and -Winline so that the warnings that should be fixed for 2.2 are more obvious. -Winline is unimportant, but -W gives thousands of warnings for comparisions. Turning off -W also loses warnings for: - auto variables clobbered by longjmp. Not much of a problem in the kernel. - functions returning without a value. I don't like losing this. - an expression statement or the left side of a comma operand contains no side effects. Turning this off also stops warnings for the low quality debugging macros in gsc.c and lpt.c. Should be in 2.2. 1996-11-11 15:49:27 +00:00			`CWARNFLAGS?= -Wreturn-type -Wcomment -Wredundant-decls -Wimplicit \`
