+Subject: [PATCH] libnm-std-aux: Adjust signature of _nm_assert_fail_internal
+
+the LSB states __assert_fail is:
+const char*, const char*, unsigned int, const char*
+https://refspecs.linuxbase.org/LSB_5.0.0/LSB-Core-generic/LSB-Core-generic/baselib---assert-fail-1.html
+
+musl uses a signed int instead. however, this is ok:
+https://www.openwall.com/lists/musl/2019/03/04/6
+
+nevertheless, since the application redefines __assert_fail, we have to make
+the types match. (not upstreamable as the opposite breaks glibc)
+
+Upstream-Status: Inappropriate [musl specific]
+Signed-off-by: Khem Raj <raj.khem@gmail.com>
