- Subject: Minor C++ PATCH to tsubst of DECLTYPE_TYPE
While working on the latest 52748 patch, it occurred to me that using
tsubst_expr for DECLTYPE_TYPE is wrong, since that function deals with
statements; since we only have to deal with expressions there,
tsubst_copy_and_build is a better choice.
Tested x86_64-pc-linux-gnu, applying to trunk.
