Hi :
I am having problems limiting the warning messages i receive
from g++. If I use -w with any other -Wwarning option i still get no NO
warning messages of the type I desire. If I don't use -w, I am swamped
with warning messages i don't want . Surely there must be a simple way
to just get a few selected warning messages easily ??
Cheers;
Robert Somerville

Like most software, how to use GCC is documented in its manual:
http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html
Which says:
"You can request many specific warnings with options beginning `-W',
for example -Wimplicit to request warnings on implicit declarations.
Each of these specific warning options also has a negative form
beginning `-Wno-' to turn off warnings; for example, -Wno-implicit."
