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."
