Building with musl libc leads to some build errors:
setrans_client.c: In function ‘receive_response’:
setrans_client.c:147:19: error: implicit declaration of function
‘readv’ [-Werror=implicit-function-declaration]
while (((count = readv(fd, resp_hdr, 3)) < 0) && (errno == EINTR)) ;
^~~~~
and:
In file included from matchpathcon.c:10:0:
/usr/include/sys/errno.h:1:2: error: #warning redirecting incorrect
#include <sys/errno.h> to <errno.h> [-Werror=cpp]
#warning redirecting incorrect #include <sys/errno.h> to <errno.h>
^
Fix the first one by including <sys/uio.h> and the second one by using
<errno.h> instead of <sys/errno.h>.
