Greetings,

the following will fail to build with recent cygwin (works with
cygwin-legacy though) :

$ cat > t.c
#include <rpc/rpc.h>

int main(int argc, char *argv[])
{
  return 0;
}
^D
$ make t
cc     t.c   -o t
In file included from /usr/include/rpc/rpc.h:61,
                 from t.c:1:
/usr/include/rpc/svc.h:83: error: field `xp_raddr' has incomplete type
make: *** [t] Error 1

the problem being that xp_raddr is being defined as "struct sockaddr_in"
and that is not being defined on cygwin's version of rpc.h (it is upstream,
on linux and opensolaris)

there is a changelog entry from 2003 that mention that include was added
and later removed but couldn't find any more references to it to know about
the rationale behind it.

Carlo

CC Sam who did the change and hopefully could help give some more context
