I'm still learning :)

Anyway, I've installed two versions of cygwin on the same machine - the
first was installed around Oct. 3 and the second one from a few days
ago. Compiling exactly the same software on both versions gives success
on the older installation and failure on the newer one. Could it be that
newer versions of some libs/compilers have bugs? Something different
between those two versions is for sure causing the problem.
Oviously, I'm using gfortran for building FLEXPART_GFORTRAN but I've
also installed from source the latest version of "jasper" and "grib_api"
libs (required by my FLEXPART software), and I'm not sure in detail what
is involved in building those libs.

Do you have any immediate idea of what could be the potential problem?

Cheers,
Kåre
