i'm trying build c++ file using in android application on jni. i'm building in windows using cygwin. i'm new , don't know doing.

here's part of output:

$ g++ -c test_wrap.cxx -i"c:\dev\android-ndk-r4b\build\platforms\android-4\arch-arm\usr\include" -i./include in file included c:/dev/android-ndk-r4b/build/platforms/android-4/arch-arm/usr/include/sys/_types.h:40,                  c:/dev/android-ndk-r4b/build/platforms/android-4/arch-arm/usr/include/stdint.h:32,                  c:/dev/android-ndk-r4b/build/platforms/android-4/arch-arm/usr/include/sys/types.h:34,                  c:/dev/android-ndk-r4b/build/platforms/android-4/arch-arm/usr/include/strings.h:42,                  c:/dev/android-ndk-r4b/build/platforms/android-4/arch-arm/usr/include/stdlib.h:42,                  test_wrap.cxx:160: c:/dev/android-ndk-r4b/build/platforms/android-4/arch-arm/usr/include/machine/_types.h:44: error: conflicting declaration 'typedef long unsigned int size_t'/usr/lib/gcc/i686-pc-cygwin/3.4.4/include/stddef.h:213: error: 'size_t' has previous declaration `typedef unsigned int size_t' c:/dev/android-ndk-r4b/build/platforms/android-4/arch-arm/usr/include/machine/_types.h:44: error: declaration of `typedef long unsigned int size_t'/usr/lib/gcc/i686-pc-cygwin/3.4.4/include/stddef.h:213: error: conflicts previous declaration `typedef unsigned int size_t' c:/dev/android-ndk-r4b/build/platforms/android-4/arch-arm/usr/include/machine/_types.h:44: error: declaration of `typedef long unsigned int size_t'/usr/lib/gcc/i686-pc-cygwin/3.4.4/include/stddef.h:213: error: conflicts previous declaration `typedef unsigned int size_t' c:/dev/android-ndk-r4b/build/platforms/android-4/arch-arm/usr/include/machine/_types.h:46: error: conflicting declaration 'typedef long int ptrdiff_t'/usr/lib/gcc/i686-pc-cygwin/3.4.4/include/stddef.h:151: error: 'ptrdiff_t' has previous declaration `typedef int ptrdiff_t' c:/dev/android-ndk-r4b/build/platforms/android-4/arch-arm/usr/include/machine/_types.h:46: error: declaration of `typedef long int ptrdiff_t'/usr/lib/gcc/i686-pc-cygwin/3.4.4/include/stddef.h:151: error: conflicts previous declaration `typedef int ptrdiff_t' c:/dev/android-ndk-r4b/build/platforms/android-4/arch-arm/usr/include/machine/_types.h:46: error: declaration of `typedef long int ptrdiff_t'/usr/lib/gcc/i686-pc-cygwin/3.4.4/include/stddef.h:151: error: conflicts previous declaration `typedef int ptrdiff_t'

can please give me hand?
