Thanks for the patch - I only have a few general, minor comments. As
noted at http://gcc.gnu.org/lists.html C++ library patches should go
to the libstdc++ list as well as gcc-patches, so I've CC'd that list
(original mail and patch are at
http://gcc.gnu.org/ml/gcc-patches/2014-04/msg01128.html)

Patches should not include generated files such as configure, as the
diffs don't always apply cleanly and the changes are implied by the
patches to files such as acinclude.m4 and configure.ac. The
regenerated versions should of course be committed, and the ChangeLog
should mention they are regenerated, as you've done.

The changelog text should be correctly capitalised and sentences ended
with a period (e.g. "New target." and "New." not "New target" and
"new"). The individual ChangeLog entries at
http://leaf.dragonflybsd.org/~marino/gcc-df-target/changelog_entries/
would generally be used as the commit message, grouped and prefixed by
the name of the sub-directory:

gcc/
        * config.gcc (*-*-dragonfly*): New target
        etc. etc.

libcilkrts/
        * runtime/os-unix.c (__DragonFly__): New target
        etc. etc.

libgcc/
        * libgcc/config.host (*-*-dragonfly*): New target
        etc. etc.


The libstdc++ changes are OK for trunk if the rest gets approved.
