I have found it impossible to install 5.1.6 and then install gcc 4.4.0 over the top and still have a working 4.4.0 compiler. it just doesn't work.
please make a working installer-based build or compiler package (at least a zip file) of the whole 4.4.0 compiler & utilities set available. even better if I could uncheck items I don't want, such as pdcurses, gdb, guile. If not, I can simply find and delete those.
even better would be the 4.4.3 release (the current release), but I would be happy with 4.4.0 since it contains TR1 and would match mingw-w64.
the documentation for TR1 (actually thw whole C/C++ library sets is at http://www.dinkumware.com/manuals/
a link via a .url file would be a very good idea I think.
