Suppress warnings #688

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Lots of warnings have been cleaned up, but there are a few more.  Attached 
patches clean then up.  

Patch #4 may be controversial, as it redefines PROGMEM.  This is the suggested 
workaround from the GNU bug tracker.  Also, the bug has finally been fixed in 
avr-gcc so will hopefully start showing up in avr-gcc releases.

I tried the same approach of redefining PROGMEM, and found that it has the same 
problem as declaring the variable extern before defining it: both are illegal 
to use for declaring variables inside functions. The best way is to upgrade the 
compiler. My attempt to compile avr-gcc 4.6.2 so far failed though.

I'm not seeing most of these.  Maybe some were fixed by other patches?

Just did a clean build on a fresh pull.  Build output attached.  Turn on -Wall 
-Werror to see them all.

I fixed most of these:

https://github.com/arduino/Arduino/commit/cce4ef7c6932c8d93c180ce7990261223e490d
63

Honestly, though, most of them weren't even showing up for me at all (even with 
-Wall) so I probably skipped some.
