I'm confused.  It looks like the argument is already quoted and this change just 
adds the ^ and $ anchors.  I don't see these ac_fn_c_check_* errors unless I 
manually remove the [] quoting.

Did this commit message get copied from xserver commit 
8c51b886400c5962b31ff565771be1b01a3ca8fb ?

This seems fine as a standalone change.
