Looks like the issue's mostly __BEGIN_DECLS & __END_DECLS,
which glibc does thus:
#ifdef __cplusplus
# define __BEGIN_DECLS extern "C" {
# define __END_DECLS }
#else
# define __BEGIN_DECLS
# define __END_DECLS
#endif
(Also, sys/cdefs.h exports c90 functions in namespace std, and does other stuff to let headers work with both C & C++).
Besides that, configure has no idea how to handle musl or the machine name, and the chroot I'm using needs fixing...
