Michel, thank you very much for the helpful suggestions and comments.
I am back in business now, albeit with an incremental, one source file at a time, approach to editing for conformance to the gcc tool chain. But nonetheless availing of navigation and refactoring features not found in the other Fortran development environment i use..

Daniel Harenberg and I have reported similar problems.
We have both installed 6.0.7 and found that not all problems were solved
for old and complicated projects but that there were some progress.
Version 7.0 is available for test. Please have a look at the
announcement by Jeffrey Overbey in the archives of this list to find
where you can get it.

You have to add http://download.eclipse.org/tools/ptp/updates/helios in
Window / Preferences / Install/Update / Available Software sites, before
Help / Check for updates

If You do not need to address more than 2 GB of memory you can stick to
Win32 (even if you have a 64 bits version of Windows) and cygwin is good
for that. I would just advise you to upgrade to gcc4 and gcc4-fortran
4.5.0-1 (by clicking repeatedly on the box next to their lines in
setup.exe of cygwin (default version is 4.3.4).
If you really need Win64 fortran binaries then it is a bit more complicated.
> What about parameters to the tool chain processes?
If cygwin is correctly installed I do not remember any additional
parameter to set but I did that quite some time ago (I (sometimes) use a
mixture of Win32 cygwin and Win64 Mingw that I would not recommend since
I have to edit my PATH environment variable from time to time (but I
mainly develop under Linux)).

Mingw is not as complete as Cygwin (unless you also install MSYS) and
there may be problems for additional utilities that you have to install
using configure or Cmake.
However, You can have Win64 versions of Mingw which you do not have for
cygwin.
