I've just tried upgrading to 5.2.0 from 5.1.0. I simply downloaded the new SDK's zip file, extracted it next to the old one, and adjusted my makefile to reflect the new path.
I get a bunch of warnings and errors in S110/*.h because of asm operand constraints or something. Of note, I am using my own custom Makefile. It has been working perfectly fine. I don't suspect it to be the problem unless the build system expectations have changed since 5.1.0.
What I find really weird is the that S110 files have not changed at all (expected) but the errors seem to be happening there.

Anyone have any clue what could have changed?
