ISO C 90 (or C-99 without GNU-extensions) compatibility fix:

* change all casts using the typeof() keyword to their respective typename
 * append a compiler flag for GCC (-fno-gnu-keywords) which disables GNU-specific keywords (typeof and asm only in case of C-99, inline as well if C-90 mode is used), to aid in code portability (i.e. among compilers)
