[Olsr-dev] Android NDK does not support -Wdouble-promotion, -Wjump-misses-init, and -Wtrampolines

[Hans-Christoph Steiner]

Hmm, ok, that explains something.  The warning removing script worked on
the build server, but not on my Ubuntu/precise laptop, I don't know why
yet...

I've never dealt with any project that has such elaborate gcc warnings.
 I'm curious what about olsrd needs this level of warnings, can anyone
illuminate me?
