Bug ID: 93590
Summary: [diagnostic] The header <codecvt> is deprecated since
C++17, but no warning for #include-ing it
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: alisdairm at me dot com
Target Milestone: ---
C++ currently has two deprecated C++ headers, <codecvt> and <strstream>.
For quite a while, gcc has warned on #include <strstream> with:
warning: #warning This file includes at least one deprecated or antiquated
header which may be removed without further notice at a future date. Please use
a non-deprecated interface with equivalent functionality instead. For a listing
of replacement headers and interfaces, consult the file backward_warning.h. To
disable this warning use -Wno-deprecated. [-Wcpp]
It seems inconsistent to not get the same warning for #include <codecvt>, at
least if the language dialect is C++17 or later.
