title: mupdf for android: ndk-build problem (error: redefinition of typedef....)
body: <p>I am following the necessary steps to have MuPDF for Android. MuPDF is built on my system, I am able to exploit it with C++, now trying with Android. All steps in the README successfully followed but when I get to step 10, that is when I have to do <code>ndk-build</code>, I get some errors:</p>
  
  <pre class="lang-none prettyprint-override"><code>/home/pc/sviluppo/android-ndk-r6b/platforms/android-8/arch-arm/usr/include/stdint.h:53: error: redefinition of typedef 'uint32_t'
  /home/pc/sviluppo/mupdf-0.9/android/jni/../../thirdparty/jbig2dec/os_types.h:46: note: previous declaration of 'uint32_t' was here
