That's accepting it.  It should be (and I think was) a hard error in gnu89
mode.

I consider this of marginal utility, but also doubt that someone is going 
to implement a configure test that uses acceptance of "inline inline" to 
decide whether the compiler has C99 inline, so a patch that keeps the hard 
error in gnu89 mode (with a testcase that it is a hard error in gnu89 
mode) will be accepted.

(The last patch to accept C99 syntax without implementing the semantics -
RTH's conditioning the pedwarn-if-pedantic for VLAs on not being in C99
mode - just swapped one set of complaints (about the pedwarn in C99 mode)
for another (that the cases not permitted by C99 didn't get warned for at
all).)
