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

[Hans-Christoph Steiner]

Why do we need to have the warning flags individually specified?  I
think it would be safer to use -Wall, then use -Wno-foo to only specify
warnings we don't want.  That way we don't have to manage the
differences in toolchains.

Here's what Android NDK's gcc has to say:

[CC] src/common/autobuf.c
cc1: error: unrecognized command line option "-Wdouble-promotion"
cc1: error: unrecognized command line option "-Wjump-misses-init"
cc1: error: unrecognized command line option "-Wtrampolines"
