-Subject: [PATCH 1/2] Replace __BEGIN_DECLS and __END_DECLS with extern "C".
-
-The macros __BEGIN_DECLS and __END_DECLS are a GNU-ism found in
-glibc and uClibc, but not musl.  We replace them by the more general
-extern "C" { ... } block exposed only if we have __cplusplus.
-
-Forward ported from a patch by Anthony G. Basile <blueness@gentoo.org>.
