can't remove all of the warnings, we permit file by file (and warning by

You can disable a single warning type in a particular file by using GCC
pragmas. If a warning can be disabled with a pragma, then the switch to use
will be listed in the error message you receive from the compiler. Pragmas

with non-gcc compilers, and can be disabled if desired. For example:

#endif
