"register" is part of the language standard, if a compiler considers it

Yes, but since C98/99 its free to the compiler simply ignoring
'register'. That means it is the right to the compiler to replace the
keyword register with white space.
Not quite. If you attempt to take the address of a register variable the
compiler is required to produce a diagnostic. Apart from that, just it
can ignore it.
Oh, and I assume you meant C89 not C98 since I don't believe this has
changed.
