[Scummvm-devel] compiler options usage

Tue Jan 6 09:51:39 CET 2015

Well, this is not quite correct, since the options are platform-dependent
in some cases, e.g. for instance, AmigaOS is adding -Wno-format, PS2 port
adds -Wno-unused-parameter -Wconversion, -Wuninitialized, etc.

In other words, study configure and resulting config.mk.
