Nah.  It's not even pedantic.

``gcc \
	-Wall -ansi -pedantic \
	-Wbad-function-cast \
	-Wcast-align \
	-Wcast-qual \
	-Wchar-subscripts \
	-Wconversion \
	-Werror \
	-Winline \
	-Wmissing-declarations \
	-Wmissing-prototypes \

	-Wpointer-arith \
	-Wredundant-decls \
	-Wshadow \
	-Wstrict-prototypes \
	-Wwrite-strings

# Use these for code that has to be compilable with K&R compilers:
# -Waggregate-return -Wid-clash-7 -Wtraditional''

is _pedantic_.  I use something like the above in my gccw script.

>> "Consider parentheses around assignment used as truth value", or

I like this.  OTOH, I hate the one about && vs || and always turn it off
in my local cc1 binaries.

I haven't seen this.  ANSI defines null pointer constants quite well and gcc
implements them quite well.
