trunk build failure on Solaris 2.6

[Katsumi Yamaoka]

Hi,

I don't know at all what's going on but this change

2007-10-17  Chong Yidong  <address@hidden>

        * configure.in (HAVE_RES_INIT): Define if res_init() exists.
        (HAVE_LIBRESOLV): Also define if we are using res_init().

makes Solaris 2.6 with Gcc 3.3 use res_init and fail to build
Emacs trunk.

config.log

Undefined  first referenced

res_init       process.o  (symbol belongs to implicit dependency

ld: fatal: Symbol referencing errors. No output written to temacs

Removing the `#define HAVE_RES_INIT 1' line in config.h does the
trick.  Does adding something to s/sol2*.h solve it?  Sorry, I
have no Solaris machine other than 2.6 (this is in the office,
so I cannot fiddle it in the week end).
