I am attempting to build Samba 4.2.0 RC4 (I have not tried previous
versions yet) and after applying attached patches the build fails with
(full build and configure output attached).

[2006/3812] Compiling lib/nss_wrapper/nss_wrapper.c
../lib/nss_wrapper/nss_wrapper.c:2405:5: error: conflicting types for
In file included from ../lib/nss_wrapper/nss_wrapper.c:65:0:
/usr/include/netdb.h:238:17: note: previous declaration of
'gethostbyname_r' was

The prototype in Samba source is:

int gethostbyname_r(const char *name,
                    struct hostent *ret,
                    char *buf, size_t buflen,
                    struct hostent **result, int *h_errnop)

Whereas the prototype in the system header is:

struct hostent  *gethostbyname_r
        (const char *, struct hostent *, char *, int, int *h_errnop);

I see that this has been discussed before on samba-technical for Solaris
11.1 which shares a common ancestor with SmartOS/illumos.

I have checked the uid_wrapper git repo (the 1.1.0 tag) and do not see
tests of the prototype as indicated in the message.  Am I missing where
this was done?  If it is not done, how do we proceed in getting this issue
fixed, because as far as I can tell this is a show stopper for 4.2 on
SmartOS and presumably the illumos family and with 3.6 being EOL'd SmartOS
will not have any supported Samba version available.
