Arnout Vandecappelle 13aca2f2e9 owfs: remove include of rpc/netdb.h
owfs carries a copy of netdb.h from an old glibc, which is only used
to implement getaddrinfo on platforms that miss it (Solaris 7 in
particular). Since all of our libc implementations have getaddrinfo,
we don't need it.

To make the patch minimal, just include if !HAVE_GETADDRINFO.

Subject: [PATCH] compat.h: only include compat_netdb.h if needed
compat_netdb.h is added for only one reason: to provide the definitions
for getaddrinfo, in case it is not provided by the system.
compat_netdb.h is just a copy from an old glibc version, but that makes
it incompatible with other standard C libraries. For example, uClibc
without RPC support doesn't have the rpc/netdb.h header. This leads to
build errors.
To work around this, only include compat_netdb.h when needed, i.e.
when getaddrinfo isn't provided natively.
Note that this getaddrinfo compat was introduced in commit bc54c431 to
support Solaris 7. Starting from Solaris 8, however, getaddrinfo is
available natively, and it's available on MacOS, Windows and any other
POSIX-2001 compliant system as well. So it may be worhtwhile to remove
it altogether.
