I got a build warning in Python Jamfile which is fixed by:
https://github.com/boostorg/python/commit/d515eb82c8a1e007651b1e7d75a3141fdc0c7ab3#diff-42dd6ec1330a7c47aaccf2ab2b8f1e02

I got this warning:

I got this error:

I guess b2 when trying to deduce compiler settings stumbles over
'cxxflags=-arch i386 -arch x86_64'. In case that's accepted behavior,
how could I specify architectures for a fat library?

When compiling for Android with API level 14 (~Android 4.0.0) and NDK
r16b I see the following error:

I'll have a look at the Android error myself, but would like to get some
feedback for the b2 vs. -arch issue.

Thanks,
