/* PR middle-end/98166: bogus -Wmismatched-dealloc on user-defined allocator
and inlining
Verify that the allocator can be declared inline without a warning when
it's associated with a standard deallocator. Associating an inline
deallocator with an allocator would cause false positives when the former
calls a deallocation function the allocator isn't associated with, so
that triggers a warning on declaration.
