the Microsoft Visual C/C++ linker via the -export-symbols argument to
the libtool script, thus matching how .def files are handled when
using GNU tools.
+ - Recognize more variants (e.g. those starting with a LIBRARY statement)
+ of module-definitions (.def) files when using them instead of a raw
+ list of symbols to export.
