Good question. Short answer: "probably not". The runtime library is
backwards compatible, so when you upgrade (e.g.) mingw32-libz-dll it
will pull in the new mingw32-libgcc-dll-1 package.
Now, there was a re-arrangement; in the past, libgcc_s-dw2-1.dll was
shipped as part OF the mingw32-gcc-bin package. Now, the dll is in its
own package. Since you are "installing" the new package -- but not
upgrading the old gcc -- you'll end up clobbering your 4.$old copy of
libgcc_s-dw2-1.dll with the new one.
But that's ok, because...the new one is backwards compatible.
So I *think* you'll be fine. But...you might want to back up your
current C:\MinGW before upgrading, just in case.
