Modern compilers can compile tail calls of unknown functions (i.e. function pointers) to jumps; so instead of using "computed gotos" (which IIRC is a GCC extension), one can use ANSII C and get more efficient code (because of control of registers)

Correct, and it's always been a gaping hole in the standard, in my opinion. Computed GOTO would be one of the more useful things added to C.
