           Summary: C++ compiler gets g++ switch even if it isn't g++
           Product: gcc
           Version: 4.5.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jay.krell@cornell.edu


if C compiler is gcc and C++ compiler is not g++, C++ compiler gets g++ flags
(maybe redirect to autoconf?)

export CXX=/usr/bin/CC
gcc-4.5.1/configure -enable-build-with-cxx

seems a bit off.

I'm trying now with CXX=CC, CC=cc.
The autoconf log is looking better.
