If you had to do this workaround your xml2-config script is probably
buggy. It should work something like this:

> xml2-config --cflags
-I/usr/local/hacks/include/libxml2/libxml -I/usr/local/hacks/include/libxml2

I see that you use cc as the compiler. I presume that cc on your
machine is a compiler from Sun. You could probably save yourself
from trouble by using gcc instead.

This is strange, your compiler should look in /usr/local/include
automaticly. On my machine both Suns compiler and gcc does that.

But if you have to work around it you should ne able to use the
ordinary features of the configure script to set arbitrary compile
flags. If you run bash or something like it you could run configure
like this:

CPPFLAGS="-I/usr/local/libpng-1.2.2/include" ./configure

or with help of env (in case you use tcsh for example):

env CPPFLAGS="-I/usr/local/libpng-1.2.2/include" ./configure

For reference these are some of the variables that configure honour:

 - Variable: CFLAGS
     Debugging and optimization options for the C compiler.

 - Variable: CPPFLAGS
     Header file search directory (`-IDIR') and any other miscellaneous
     options for the C preprocessor and compiler.  

 - Variable: CXXFLAGS
     Debugging and optimization options for the C++ compiler.  

 - Variable: LDFLAGS
     Stripping (`-s') and any other miscellaneous options for the
     linker. 

 - Variable: LIBS
     `-l' and `-L' options to pass to the linker.
