Change void*-typed function pointers to void_fp. - Updated all instances of void* variables that store function pointers to variables of a new type, void_fp. Originally, I wanted to define the type of void_fp as "void (*void_fp)( void )"--that is, a pointer to a function with no return value and no arguments. However, once I did this, I realized that gcc complains with incompatible pointer type (-Wincompatible-pointer-types) warnings every time any such a pointer is being assigned to its final, type-accurate function pointer type. That is, gcc will silently typecast a void* to another defined function pointer type (e.g. dscalv_ker_ft) during an assignment from the former to the latter, but the same statement will trigger a warning when typecasting from a void_fp type. I suspect an explicit typecast is needed in order to avoid the warning, which I'm not willing to insert at this time. - Added a typedef to bli_type_defs.h defining void_fp as void*, along with a commented-out version of the aborted definition described above. (Note that POSIX requires that void* and function pointers be interchangeable; it is the C standard that does not provide this guarantee.) - Comment updates to various _oapi.c files.
