Bug ID: 81353
Summary: Please provide a libstdc++ version macro
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: coypu at sdf dot org
Target Milestone: ---
occasionally workarounds are needed for old libstdc++ versions, it would be
easier to do so with the help of a macro.
if the compiler used is not GCC, we can't check for GCC's version.
