While building GDB from CVS on my Linux machines, I saw a few warnings
like this one:
> tracepoint.c: In function `trace_find_tracepoint_command':
> tracepoint.c:2077: warning: suggest explicit braces to avoid ambiguous `else'

with GCC 3.0.4. Hence my question, do we want to fix these warnings
anyway?
I guess for a lot of warnings, the fix are quite straghtforward, like
