The musl patches for apparmor no longer seem to work as it missing stdio_filebuf.h which is provided bt libc++stdv3 which is masked on musl systems. Reproducible: Always Steps to Reproduce: 1. setup stage3 with musl 2. emerge -va sys-apps/apparmor Actual Results: clang++ -march=nocona -O2 -pipe -falign-functions=32 -D_GNU_SOURCE -Wall -Wall -Wsign-compare -Wmissing-field-initializers -Wformat -Wformat-security -Wunused-parameter -Wimplicit-fallthrough -std=gnu++0x -c -o aare_rules.o aare_rules.cc 22 warnings generated. hfa.cc:1332:19: warning: unused function 'diff_qualifiers' [-Wunused-function] static inline int diff_qualifiers(uint32_t perm1, uint32_t perm2) ^ aare_rules.cc:26:10: fatal error: 'ext/stdio_filebuf.h' file not found #include <ext/stdio_filebuf.h> ^~~~~~~~~~~~~~~~~~~~~ 1 error generated. make[1]: *** [<builtin>: aare_rules.o] Error 1 make[1]: *** Waiting for unfinished jobs.... chfa.cc:350:3: warning: unannotated fall-through between switch labels [-Wimplicit-fallthrough] This log is using my fixes for clang but the issue does exist on a gcc musl build as well. Part of me thinks if we are masking libc++stdv3 then we need mask this as well but I wish to get more views before I submit this as a PR to make sure this is the right way forward.

I have done further tests on this by manually adding the following header files: ext/stdio_filebuf.h bits/requires_hosted.h bits/c++config.h bits/os_defines.h bits/cpu_defines.h This pushes the error on to place that may be of more help trying to find the point of failure.
