Hi Vicente.
Yes, don't use 4.5.0 - 4.5.4 headers, it's already fixed by dropping the 
connman workaround patch which isn't compatible with the proper fix, 
Thomas rebuilding the test toolchains and bumping the headers to 4.5.5.
As for covering the broken headers scenario any patch that's created for 
that is unlikely to be accepted upstream, and any toolchain that ships 
with those broken headers could be called "broken".
Regards.
