You did not indicate the content and syntax of your "--includedir" line, so I 
cannot give you feedback on what you did
wrong.

As you know, the xpm and png packages are not installed as part of the Sun 
Solaris distribution.  You have to build them
yourself and install them somewhere.  No doubt, you put them in a non-standard 
place.  So the Emacs configure script
can't find them.

By the way, you not only have to tell Emacs where to find the include files, 
you also have to tell Emacs where to find
the corresponding link libraries.  I do this with the --x-includes and 
--x-libraries command line options.  Here's how I
invoke configure to build Emacs on Sun Solaris 7:

../configure  --with-kerberos --x-includes='/home/kgallagh/include 
-I/usr/openwin/include'
--x-libraries='/home/kgallagh/lib -L/usr/openwin/lib

[Note:  its all on one line, in case it got broken in two while in transit.]
The include directory in my home directory contains all the header files of the 
extra features I build into Emacs,
except, I placed xpm.h in /home/kgallagh/include/X11.  The corresponding libs 
are in /home/kgallagh/lib.

The configure script adds a -I to the front of the --x-includes string before 
passes it to the compiler.  So, if you
specify more than one path, as I have, you must add a -I to each of the extra 
paths and then quote the whole string.
The same syntax is needed for --x-libraries.

Anyway, the above works for me.  Something similiar should work for you.
