Yes, the 'good' installation was done Oct. 3 with many more packages
than the bad one. Just a week ago I wanted to install cygwin and run my
software on other machines, and then I ran into this problem. It's not a
paradox that the good installation has earlier package versions since it
was installed a month earlier than the bad one :)
So, my problem is now to isolate what has changed since then, which is
affecting the build of my fortran binary.

There is one thing I remember that is different now when I install a
required library (grib-api, see post
http://cygwin.com/ml/cygwin/2011-10/msg00037.html) 

I did not experience this hang back one month ago, but I've upgraded gcc
since then, and I wonder if the grib_api, and then my software, is
affected by this.

I will try to rebuild everything with gcc 4.3.4 too se if it helps, and
report the result to the list.

Cheers
