That's fine if you just want a stable compiler.  But the question you
are asking seems to have morphed into "does support for a relocatable
compiler on MinGW currently work" and for any kind of "what is the state
of the code" sort of thing, you want to look at the current code (aka
HEAD aka 4.3) and not the code on a release branch, which tends to be
fairly static.  Because if you find that something doesn't work, then
you are left wondering if it is still broken in the current sources or
if it was just broken on that release branch.

Comparing 3.4 to 4.x won't really tell you much, there have been so many
changes.  The gcc packages on the MinGW site are already relocatable
(you can extract them anywhere and they work fine) and you can see
exactly how they're built with the included build script.  If anything
this just implies to me that the code to support this has bitrotted, or
there is some new bug.
