include netinet/in.h in resolver
On some platforms (notably FreeBSD) netinet/in.h is required for the struct in_addr type and IPPROTO_* constants. As this header and both required definitions are documented in IEEE Std 1003.1, this should be safe on all systems.
-
some time ago gssapi.h moved to gssapi/gssapi.h, and on some systems (e.g. FreeBSD) gssapi.h carries a deprecation #warning - which becomes a fatal error since we're compiling with -Werror
-
As far as I can tell, libresolv is not needed anymore. To avoid build breakage on systems where the resolver functions live in libc, just remove -lresolv
-
try generic cc before testing for gcc
FreeBSD has clang as it's primary C compiler (and often no gcc, these days). To avoid using the "wrong" compiler (gcc installed via ports if available), test for cc first.
-
as loudmouth is maintained in git, the whole concept of rcsid does not really apply anymore - but we get warnings from -Wunused which are promptly upgraded to errors (-Werror)
