ndk-build errors
<p>I built my C++ lib with gcc compiler without any errors in cygwin environment, but when I tried to build jni files with the lib using ndk-build tool, couple errors ocurred. One error is missing iostream.h, fstream.h and iomanip.h files. The other one is 'Your C++ compiler cannot handle class templates'. </p>

<p>Any suggestions on how to get around these issues? Thanks.</p>
