/* 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.
