Yes, the sha1 matches.
sunyc@sunyc-wks /lib/gcc/i686-pc-cygwin/4.8.2
$ sha1sum.exe libstdc++.*
f4dfadfddade3aceaf4852cd5db31372ab7ef0d1 *libstdc++.a
963e2a697c3a1a7d036d975b07f4c408bbd1cb2d *libstdc++.dll.a
Also I couldn't find GLIB_xxx version number in libstdc++.a
sunyc@sunyc-wks /lib/gcc/i686-pc-cygwin/4.8.2
$ strings.exe libstdc++.a | grep GLIB
GLIBCXX_FORCE_NEW
GLIBCXX_FORCE_NEW
GLIBCXX_DEBUG_MESSAGE_LENGTH
Cheers.
