Hi
Doing some greps and mangling on the build logs from every BSP, I
discovered we have ~2350 unique warnings output by gcc.
- ~1250 of these only occur once.
- ~1900 occur less than 5 times.
- ~2270 occur less than 10 times.
These are almost certainly in BSP specific code built for variants.
My hope is that folks take a few minutes, remove warnings from
the BSP they are using and submit a patch.
That leaves about 100 warning lines that are reported in over
ten BSP builds.
At the high end, we have a handful that show up on over 100 BSP
variants. My hope is that we can eliminate these, then focus on the
next set which impact over 50 BSP variants. I can post the full
list if someone wants to tackle a class of warnings like unused
variables, missing prototypes, etc.
Here are the warnings which occur more than 100 times:
200 c/src/../../cpukit/libmisc/shell/hexdump-conv.c:145:4: warning:
format '%lc' expects argument of type 'wint_t', but argument 4 has type

130 c/src/../../testsuites/sptests/spintr_err01/init.c:23:21:

I don't know how we have 200. There are 182 BSP log files.
Help definitely appreciated. Hopefully we can all pitch in
and reduce warnings.
Thanks.
