Where did you include the led.h file?

Could post line 768 of F:\TEST\MPC5634M_MLQB80.h? I'm guessing that whatever compiler you have selected using "mex -setup" in MATLAB does not support "char" as a bit-field type. This page talks more about C Bit Fields, and suggests that unsigned int, signed int, or int are the only legal types for bit fields unless you're using a newer compiler.
