The libtool version is the 1.5.20-2 Cygwin package.  max_cmd_len=8192.

Yes, I tried building from CVS HEAD and got a much different result. 
However, this time it still does not do any "ld -r", but it instead
tries to use "gcc -shared" for the final link.  Something else seems
broken now though, which results in literally 13000+ lines of "undefined
reference" due to the fact that linking is done with gcc instead of g++,
and there's no -lstdc++ included:
