Subject: Using modern gcc from pkgsrc on old systems for c++

I am occasionally trying to work on the compiler selection issues a bit.
As part of that, I'm trying to build a c++ program on netbsd-5, which is
ancient, as a difficult test case.  The native compiler is gcc 4.1.3.

Following Jason Bacon's lead, I have built gcc7 from pkgsrc, and am
using that via GCC_REQD=7.  (Yes, I get it that this can't be used to
bootstrap 7; I added it after 7 was built to avoid that.)

Building devel/re2c fails with messages about c++11 things not being
defined at link time.  re2c is declared to be "c++", and checks for and
passes --std=c++98 on every compile and link.  The .o file -- built with
-std=c++98 -- indeed refers to a number of c++11 looking things.

After some investigation, I found that the invocation of c++ for final
linking results in /usr/lib/libstdc++.so.6.0 being referenced (atime
update), and that's the 4.1.3 version.  If I add
/usr/pkg/gcc7/lib/libstdc++.a at the end, it links ok.  This is without
wrappers, with me running the link command cut and pasted from the build
log.  I conclude that

  - the use of functions with cxx11 in them is an internal
    implementation detail of gcc7 (which is perfectly ok, even if it
    surprised me at first that this happens on c++98 builds)

  - somehow, gcc7 is linking the system libstdc++, instead of its own,
    despite what the search paths seem to say

The second thing I don't understand, because all of the commands show -L
for the right lib first, and the default lib path in gcc has that
earlier as well.

My question is thus: Am I understanding this correctly?  Is it
reasonable to expect "/usr/pkg/gcc7/bin/c++ -o foo foo.o" to link with
the stdc++ that belongs with that compiler?

Do I need to mark the package with USE_PKGSRC_GCC_RUNTIME?   But
doesn't every c++ program depend on libstdc++, and doesn't that have to
be the one that came with the compiler (r ABI compatible with it)?

Some data points (with GCC_REQD=7)

make USE_NATIVE_GCC=yes package: succeeds, but uses old compiler (which
  works for this package, but of course not for things in newer C++)

make package: fails to link

make USE_PKGSRC_GCC=yes package: fails to link.  seems to be exactly as
  previous (ccache reports all hits)

make USE_PKGSRC_GCC_RUNTIME=yes package: added a dependency on
  gcc7-libs.  Resulted in all ccache misses.  But still failure to link.


Here is an example of the failures when using gcc7 and not manually
inserting gcc7's libstdc++.a at the end of the link line.
