The latter. _bss_end & friends should not really be exported. > > I'd like to add that the DLL-to-be that I'm fiddling with > (libosp.dll/OpenSP) builds on Win32/MSVC and Linux etc, so I assume > that the code is prepared for building a DLL.

Take a look at the makefile in the <TOP>/ncurses/c++/ directory from the ncurses-5.2-4-src.tar.gz tarball on any cygwin mirror for a clue. Or, for a smaller download, look at http://www.neuro.gatech.edu/users/cwilson/cygutils/dllhelpers-0.2.6.tar.gz which is based on Mumit's original 0.2.5 version. Unfortunately, I've got a deadline or I'd address this question a little more thoroughly. I'll try to get back to it this weekend. --Chuck -- Want to unsubscribe from this list?
