   4 Subject: [PATCH] compat.h: only include compat_netdb.h if needed
   5
   6 compat_netdb.h is added for only one reason: to provide the definitions
   7 for getaddrinfo, in case it is not provided by the system.
   8 compat_netdb.h is just a copy from an old glibc version, but that makes
   9 it incompatible with other standard C libraries. For example, uClibc
  10 without RPC support doesn't have the rpc/netdb.h header. This leads to
  11 build errors.
  12
  13 To work around this, only include compat_netdb.h when needed, i.e.
  14 when getaddrinfo isn't provided natively.
  15
  16 Note that this getaddrinfo compat was introduced in commit bc54c431 to
  17 support Solaris 7. Starting from Solaris 8, however, getaddrinfo is
  18 available natively, and it's available on MacOS, Windows and any other
  19 POSIX-2001 compliant system as well. So it may be worhtwhile to remove
  20 it altogether.
