  collect2 is to ld as gcc is to cc1, it's a driver.  Add '-v' to the collect2
command line you pasted to see the exact ld command line.

  Look around this bit in make_one():

  It gets called from pe_dll_generate_implib() according to what it's parsed
from the .def file.  Check that dlltool hasn't bogusly emitted the .def file
listing as a DATA export; otherwise the problem may be in ld's parsing and
handling of it.
