Yes, but it would also use an initializer function instead of a static
initializer.  Whether that would have any noticeable performance impact
is unclear, but w.r.t. POSIX it's clear that it's no problem to use a
static initializer, just unspecified whether the destructor is trivial
or not.  These two issues should not be mixed up in one configuration
item IMHO.
