Exception: Fatal error in parsing headers

6 warnings plus 1 error occur when I try to use llvm3.3 generate the binding code, seems warning wont affect much ,but error makes the process stop, Here is the error:

severity = Error,
    location = SourceLocation file '/path/to/android-ndk-r9c//platforms/android-14/arch-arm/usr/include/math.h', line 532, column 5
    details = "conflicting types for '__builtin_isnan'"
