Not here. It still works for me with today's trunk, as it did before.

How did you invoke the configure script? Did you use
nt/msysconfig.sh, or did you invoke ./configure by hand? I'm guessing
the latter, in which case the file nt/mingw-cfg.site was not loaded.
Please be sure to follow the instructions in nt/INSTALL.
Here's what my config.log says about this test:
configure:22741: checking whether dup2 works
configure:22811: result: yes
That's it: it never runs the test program, precisely because that
would erroneously decide that dup2 doesn't work. This happens because
mingw-cfg.site forces configure to accept this result without testing.
