[Tinycc-devel] Many new warnings since yesterday |

Yesterday, Grischka applied my patch to remove last warning (thanks Grischka),
tcc compiled with NO warning at all.
This morning, with no changes on my config (same compiler, same options, same
script to fetch mod and compile), I get many more warnings on RPi as well as on
Fedora 18 x86_64
Please note that RPi uses default unsigned char which is different than x86, so
sign warnings may be annoying
To me, a release build should be warning free. Warning free does not mean that
build is free of ALL possible warnings (for example using extra -Wxx, using
llvm or splint - I recommend splint) it means release manager is aware of
suspicious code and either, by order of priority:
- fix it
- patch it in order to make build happy
- remove offending warning flag for release (and reintroduce this flag in trunk
right after the official release)
Btw, I don't see what recent change produces those new warnings.
Here are the new warnings:
