c++: visibility wrt concept-id as targ [PR115283]
Like with alias templates, it seems we don't maintain visibility flags
for concepts either, so min_vis_expr_r should ignore them for now.
Otherwise after r14-6789 we may incorrectly give a function template that
uses a concept-id in its signature internal linkage.
PR c++/115283
gcc/cp/ChangeLog:
* decl2.cc (min_vis_expr_r) <case TEMPLATE_DECL>: Ignore
concepts.
gcc/testsuite/ChangeLog:
* g++.dg/template/linkage5.C: New test.
