> I don't agree with the point that libecl.dll.a cshould not be picked up
by the linker.
> It is not necessary and you can directly link to cygecl.dll, that I
agree with, but it should be possible to go through libecl.dll.a as well.
Redhat docs recommend direct linking over the import library linking, as
more efficient.
Further than that, no Idea. I don't have much (positive :-)) experience
with Win32 dlls.

this could well be the case, e.g. {{{__declspec(dllexport)}}} declarations
missing in the source when compiling.
(and there are arcane rules about using -export-all-symbols and the above
declarations at the same time)
Or some options to the linker are wrong/missing?

> Or then I don't understand how any piece of Sage can link with MPIR,
MPFR and any other library which uses libtool and which generates as well
import files and put them into SAGE_LOCAL/lib/ where they get picked up
before anything else.
note that there are also these .la files produced along the way in the
case the libtool is used.
> And I don't think we have any piece of code which makes sure these dll.a
files are not used.
