Hi Tobias,
I tried the !GCC$ ATTRIBUTES compiler directive with various names
(mydata and x)
but nothing worked. (I already use the --export-all-symbols option)
Any other possibilties? I have not tried the option with .def files
yet, but that
seems superfluous with --export-all-symbols on.
Regards,
Arjen
