It sounds to me like the program is just failing to include <netinet/in.h>. If struct sockaddr_in is referenced by one of the musl headers but not defined, that's a bug in musl, but it sounds to me like the program is just assuming header pollution (i.e. assuming that some other header includes netinet/in.h or otherwise exposes this type. Could you clarify the error that's happening? If it is a bug on musl's end, I'll fix it. And since this may just involve the utmp.h header which is not subject to standards requirements, I might work around the problem on our end even if this is not a musl bug. Rich
