Kun,

The PATH environment variables is used only to find executables and the DLL 
(dynamically linked libraries) those executables require.


Include files required during C or C++ compilation are located via a 
separate search path maintained by the compiler and not driven by any 
environment variable, at least not in the Cygwin compiler, which is GCC.

You'll probably need to learn about the conventions and rules of C 
programming and compilers (and related tools such as "make") in order to be 
able to generalize the build scripts you're using.


By the way, is this the same CLDC whose home page is 
<http://java.sun.com/products/cldc/>? If so, are you also building the KVM 
yourself? If not, is the KVM also built with GCC? If these two components 
are not going to be built with the same compilers, then you must verify 
that the compilers' ABIs (application binary interfaces) are compatible, or 
the CLDC native library you're building will not be usable from the KVM.

It is a certainty that a Java Native Interface library built using GCC will 
not be able to be accessed from the Sun JVM for Windows.


Also, just to be pedantic, it's "Cygwin," not "CygWin."
