As a part of the ongoing process of cleaning up and improving our
handling of warnings, the time has now come to the solstudio compiler.
(I know this is not the most relevant of compilers, but I actually
started out with the warning cleanup project on solstudio, since it's a
simple, but limited, compiler in terms of options. So this is an old
personal branch that I'm finally bringing in to mainline.)
Just as we have done with gcc (-Wall -Wextra), we should increase the
general warning levels on solstudio, and then -- if needed -- disable
individual warnings. Warnings should be disabled on a per-library level
if they indicate real issues that should be fixed, or globally if they
are deemed not relevant for the project as a whole. (Unfortunately, for
solstudio, some warnings that really should be fixed applied to just
about every library, and for sanity's sake I had to disable them globally.)
I also deemed a few warnings that had previously been individually
disabled, to be dumb enough (or at least unsuitable to us) to warrant
global disabling.
I intend to open separate bugs on the owners of the native libraries
where new warnings have been disabled, since I believe they point to
real bugs, or at least sloppy programming practices, and should be
addressed.
