I don't know if it's applicable here or not but uClibc does something
"clever" with these functions.  It pulls the functions out of libgcc.a
and puts them the the C library (libc.so in this case).  This avoids the
requirement for a separate libgcc.a to some degree, although gcc still
requires it.  I just make an empty library for this case, though.

Could you do something like this with with mingwex.dll?
