Hmmm, the thing is I can't really work around this: the regex lib has a
bunch of class-template-specific static data (basically pointers to member
functions) that it needs to be able to dispatch to the correct matcher. The
warning message is wrong for several reasons IMO:

1) the function isn't inline.
2) the initialiser list can not be omitted because the data is *const*.
3) the semantics of the function should be OK, since the shared data is
const and immutable, so multiple copies are OK.

I guess you could suppress the warning by removing the "static" declarator
for these problem platforms, but it's a fix that really should not be
required, otherwise just ignore the warnings if that's acceptable to you...
