mircea_popescu: and so back to the original, there can't "not be alternatives" tognat. leaving aside the in principle argument, there's alternative by example : expose the cpu instruction and woe to anyone who won't/can't/doesn't.
asciilifeform: (same problem as gcc, but difference is, gcc will -- theoretically -- build on certain other compilers, though i have nfi when anyone last attempted this. but there are not and never were any open alternativestognat.)
