Reducer callbacks trigger spurious -Wunneeded-internal-declaration warnings #154
Description
The compiler incorrectly says static reducer callbacks used inside a template have not been emitted.
/* Unwanted warnings:
unused.cpp:9:13: warning: function 'identity_64' is not needed and will not be emitted [-Wunneeded-internal-declaration]
unused.cpp:13:13: warning: function 'sum_64' is not needed and will not be emitted [-Wunneeded-internal-declaration]
