Attempt to fix http://osvdb.org/displayvuln.php?osvdb_id=22956 Tiny C Compiler contains a flaw that may have security implications on programs compiled with it. The compiler fails to return unsigned values for the sizeof() macro, resulting in a potential integer overflows in the objects it compiles. (I.E. -1>sizeof(int) is false if signed, true if unsigned.)
