First,
The university won't let me run the

$ mkpasswd -l -d > /etc/passwd 
$ mkgroup -l -d > /etc/group 

with AD rights, so I just have to live with that.

Then, 
file FLEXPART_GFORTRAN.exe prints: PE32 executable (console) Intel
80386, for MS Windows.


I'm not even close being an expert on this, but usually I manage to
figure out something, but this time I'm totally lost...

It's about a month since I built the well working binary on the
different machine, and wonder if any upgrades of cygwin software
(compilers or anything) since then may have contain some bug. The bad
binary is built on a quite fresh cygwin install. Maybe I will try to
reinstall cygwin on the successful machine and see if a rebuilt version
of the binary fails.

Any thoughts on that?
