..., that is: decorated 'void dealloc_long(long int*)' instead of plain
'dealloc_long' -- similar to how all the other 'dg-warning's allow for the
decorated function signature in addition to the plain one.

This issue was latent since the test case was added in
commit fe7f75cf16783589eedbab597e6d0b8d35d7e470
"Correct/improve maybe_emit_free_warning (PR middle-end/98166, PR c++/57111, PR middle-end/98160)",
and was finally exposed by my recent
commit 9c03391ba447ff86038d6a34c90ae737c3915b5f
"Tighten 'dg-warning' alternatives in 'c-c++-common/Wfree-nonheap-object{,-2,-3}.c'".
