Yeah, but I want the specifically useful warnings as well :-)
>From my Makefile:
WARNING = -W -Wall -Wno-sign-compare \
-Wconversion -Woverloaded-virtual \
-Wsign-promo -Wundef -Wpointer-arith -Wwrite-strings
# -Wold-style-cast: triggered by header files for 2.95/woody
# -Wmissing-noreturn: triggered by some virtual functions.
# -Wmissing-prototypes -Wstrict-prototypes: Not C++ flags.
At some point I went through the manual and added all the warning
flags I could find, then commented out those that did not apply to my
coding style or environment. Apparently there were six additional
flags that either didn't trigger any warnings on my code, or where I
found a rewrite made the code clearer.
