Thank you.. I've realised I probably asking the wrong question...

is there an existing tool that will pull the following symbols from a
collection of .lo files:
* explicitly _declspec(dllexport) symbols
* any symbols that could be linked to the .lo files if they were collected
into a static library. (phrased badly I know)
currently libtool uses dlltool --export-all -z mydeffile.def a.lo b.lo ...
d.lo where the .lo files are what will be linked to created the .dll

the symbols are used to created import and export .def files so that the .h
files do not need to explicitly use declspec(dllimport) etc.

if there is no existing tool... can anyone recommend documentation that
might help me specify what said tool needs to do to get only those symbols?
there are T (haven't looked at D yet) symbols that are part of core system
libraries (to pick two of them T _malloc or T _strcmp). I don't think glib
(my test libtooled library overrides those function itself).
