I see that pkg-config --libs gtk+-2.0 on GNU/Linux does not include -lX11, yet 
it gets linked in because of implicit dependencies.  It may be that pkg-config 
relies on this, but the Solaris ld does not handle this the same way as GNU 
ld.  After all, the Solaris ld does seem to know which library is missing.

Anyway, the patch installed is OK, but I wonder if we will see more of these 
errors if Emacs starts to use pkg-config for more packages?
