undefined reference to '__sfp'
jni/com_googlecode_leptonica_android/stdio/fopencookie.c:154: error: undefined

reference to '__sfp'
collect2.exe: error: ld returned 1 exit status
make.exe: *** [obj/local/armeabi/liblept.so] Error 1
these variables (__sfp , ____sflags) seem to not being defined in the project.

What version of the product are you using? On what operating system?
tesseract-ocr-3.02.02.tar.gz
leptonica-1.69.tar.gz

I'm running on win seven 64bits

Please provide any additional information below.
I used ndk-build -version = GNU Make 3.81
