Uncommon but useful GCC command line options – part 2

If you recall, in the beginning of the first part of this tutorial series, I briefly mentioned that the -Wall option that developers generally use for generating warnings doesn’t cover some specific warnings. If you aren’t aware of these warnings and have no idea on how to enable them, worry not, as we’ll be explaining all that in detail in this article. Aside from this, we’ll also be covering a gcc warning option related to floating point variables, as well as how to better manage the gcc command line options if the list grows large.
