+Subject: [PATCH] src/Gtrace: remove unguarded print() calls
+
+There is a use of printf() without #include stdio.h in src/arm/Gtrace.c,
+which results in a compiler error if clang 16 is used:
+
+src/arm/Gtrace.c:529:7: error: call to undeclared library function
+'printf' with type 'int (const char *, ...)'; ISO C99 and later do not
+support implicit function declarations [-Wimplicit-function-declaration]
+
+Replace the printf("XXX") with a Dprintf, so it doesn't pull stdio in
+unless in a debug build, and reword the message to be clearer.
+
+Also there is another printf("XXX") inside a FreeBSD-specific block in
+the UNW_ARM_FRAME_SIGRETURN case, replace this with a #error as the code
+needs to be implemented.
+
+Fixes #482.

+Subject: [PATCH] If you:
+
+TCLIBC=musl bitbake unwind
+TCLIBC=musl bitbake gcc-runtime -c cleansstate
+TCLIBC=musl bitbake gcc-runtime
+
+you will see libstdc++ fail to build due to finding libunwind's header file.
+
+Khem: "When we build any of gcc components they expect to use internal version
+and that works with glibc based gcc since the search headers first look into gcc
+headers, however with musl the gcc headers are searched after the standard
+headers ( which is by design the right thing )."
+
+This patch hacks around the issue by looking for a define used during gcc-runtime's
+build and skipping to the internal header in that case.
