I get no differences in warnings from the bad build compared to the good one, so I really don't know what to look for. So far I have come to the conclusion that this must be related to one or several changes in the cygwin distribution done after October 3. Through try and failure testing I found that this is not affected by gfortran/gcc as both gcc 4.3.4 and gcc 4.5.3 works. The latter hangs on '$EGREP' calls in the 'grib_api' (required library) configure script, but the workaround of changing to 'egrep' works fine. I have posted the output from strace, objdump and cygcheck for some of you to look at in the former thread, but it seem like this is far from a straight forward problem. I can see from the [ANNOUNCEMENT] posts that a few things in this cygwin distro have been updated since October 3 and I kindly ask if someone have an idea of what updates since then may cause a badly gfortran built binary if it has nothing to do with gcc alone? I will now start going through the updates and change back to versions yielding October 3 if possible. I think this is important since cygwin will give the opportunity to run and develop FLEXPART on Windows machines the way linux-users are used to. In addition, I also see a potential problem of other fortran software that people want to run under cygwin. Regards, Kåre
