That libgcc_s_dw2-1.dll is the problem, I think.  I think this might
be the same issue as summarized here:

  http://sourceforge.net/mailarchive/message.php?msg_id=31010191

and in the links in that message.

Alternatively, perhaps you have conflicting versions of
libgcc_s_dw2-1.dll on your system.

Questions:

  . Did you install a different version of GCC, as part of your MinGW
    re-installation?  If so, which GCC version do you have now, and
    which one did you have before?

  . Does temacs.exe you produce depend on libgcc_s_dw2-1.dll?  (Use
    the dependency walker or objdump to find out.)  If not, perhaps
    some libraries that Emacs loads depend on that DLL?

  . If you add -shared-libgcc switch to the temacs link command line,
    does the problem go away?
