Mainline: C++ include files not found!

[Gerald Pfeifer]

If I invoke gcc/g++ using a symlink (for example, ~/bin/gccvs pointing to
the actual location of the binaries which is _not_ in my path), gcc/g++ no
longer find C++ include files:

  % cat x.cc
  #include <iostream>
  #include <string>
  #include <set>
  #include <functional>
  #include <sstream>
  main() { }

  % gccvs x.cc
  x.cc:1:20: iostream: No such file or directory
  x.cc:2:18: string: No such file or directory
  x.cc:3:15: set: No such file or directory
  x.cc:4:22: functional: No such file or directory
  x.cc:5:19: sstream: No such file or directory

  % ls -ld `which gccvs`
  ... /home/pfeifer/bin/gccvs -> /sw/gcc-current/bin/g++
  % /sw/gcc-current/bin/g++ x.cc
  %

Daniel, might this be related to your recent changes wrt. sysroot?

PS: Here is the output of gccvs -v x.cc:
