And also error when I add "-g"
Excellent, thanks for the feedback. I believe that the modified
configure test will solve this issue, and will be monitoring
gcc-testresults for confirmation.

But error when I add "-g" to
Weird. Does -std=c++0x or -std=gnu++0x make a difference?
I'm trying to figure out why I see this warning/error for things like
17_intro/headers/all_c++200x_compatibility.cc
but not always.

This is actually a useful warning, since -ffunction-sec
This is actually a useful warning, since -ffunction-sections not only
affects debugging but also adds unnecessary size to executables on
PE-COFF targets (and others where ld does not support --gc-sections).
One way to avoid is to add --enable-cxx-flags='-fno-function-sections
-fno-data-sections

Hey. I'm looking at some of the new fails on cygwin and AIX. Both of
these platforms have fails that don't happen on linux. These fails
look like:
