Great! Thank you.

Unfortunately ld does not understand forward statements in the def files,
it just crashes:

-- start of foo.def --
LIBRARY foo.dll

EXPORTS
    foo_export1@4
    foo_export2@4=bar.function@4
-- end of foo.def --

ld: foo.def:5: parse error
      0 [main] ld 304 handle_exceptions: Exception: STATUS_ACCESS_VIOLATION
   1201 [main] ld 304 stackdump: Dumping stack trace to ld.exe.stackdump

Using dllwrap helps to eliminate problem with forwards, but functions
in the export table have @ decorations again. I call dllwrap this way:

dllwrap --def foo.def -Wl,--kill-at $(ALL_OBJS) -o foo.dll

Specifying -Wl,--kill-at in the --driver-flags starts emit huge number of
error messages, which apparently mean that I need specify *ALL* defaults,
generally passed by dllwrap.

Certainly ld should be fixed to handle forwards in the .def files,
but I would be happy, if dllwrap could pass --kill-at directly to ld.
That would solve all my current troubles.

Again, thanks for your help.
