MinGW error Type '__m128i' could not be resolved in eclipse -

in eclipse mingw trying compile c code having intel intrinsic instruction (sse2 sse3). have given compiler option -march=native -msse2 -msse3 -mssse3 -msse4.1 getting error

type '__m128i' not resolved.

still able build application crashing @ runtime while executing intel intrinsic instruction. have go through header files of intel intrinsic instruction showing "sse3 instruction set not enabled".

please me out of this.
