Yeah, that is a problem. They did add them to GCC (not only Clang) 
though, and as far as using GCC extensions, most compilers adopt them 
one way or the other. Hopefully, they will be imported from the Apple 
branch of GCC to the mainline.

Many things in GCC are just incredibly useful, including the vector_size 
attribute, and people are using them, it is not a matter of being non 
standard, but rather that the extensions are good enough that enough 
vendors implement them.

I think that the blocks are crying out for standardisation, maybe not by 
ISO, but by some informal means between compiler vendors.
