+Subject: [PATCH] iprlib: fixes for compatibility with musl
+
+<bits/sockaddr.h> is an internal C library header, which is not
+guaranteed to be available in all C libraries, so it shouldn't be
+included, otherwise iprutils cannot be built with musl.
+
+<limits.h> is needed to get the definition of PATH_MAX.
