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:

Yes. You've run afoul of this chunk:
(init_standard_includes): Handle add_sysroot. Do not
add unrelocated copies of relocated directories.
Unfortunately, we can't just yank that part - it's a bug fix; without
it, a relocated include directory that should be searched after
$prefix/include would be searched before it instead.
Folks, should we explicitly use readlink to follow if argv[0] turns out
to be a link? I guess that's reasonable. I'm thinking of doing it
directly in make_relative_prefix.
