Because in most ABIs, a function pointer is a pointer to the first instruction. The notable exceptions are: - PowerPC and PowerPC64 with AIX ABI, - ia64 - hppa, hppa64.

As far as I understand, this [1] would be a profound change of the C language. Possibly people feel that C shouldn't evolve in an uncontrolled and crazy way like C++ does...
