+Subject: [PATCH] Proper detection of cxxabi.h and execinfo.h
+
+The current code in webrtc/base/checks.cc assumes that if __GLIBCXX__ is
+defined and __UCLIBC__ is not defined, then both cxxabi.h and execinfo.h
+will be available.
+
+Unfortunately, this is not correct with the musl C library:
+
+ - It defines __GLIBCXX__
+ - It does not define __UCLIBC__ (it's not uClibc after all!)
+ - But it also doesn't provide execinfo.h
+
+Therefore, in order to make things work properly, we switch to proper
+autoconf checks for cxxabi.h and execinfo.h, and only use the backtrace
+functionality if both are provided.
