I was able to build under cygwin by removing the use of -no-undefined from the cygwin rule in

Seems like there was a change in gcc that made this an error.

There's discussion in that thread about the correct way to fix this and I wasn't quite clear if my approach was right, so I didn't include a patch.  LRN, who was in on this discussion might have some perspective.

You shouldn't need plibc on Cygwin, the change from 2011 sounds like
the right thing.

I've just built a MSYS2 version of libmicrohttpd, it detected pthreads
at configure time correctly. MSYS2 (and Cygwin) provides pthreads as
part of the main runtime, so it's impossible to miss.

That said, i don't use x86_64 versions of either MSYS2 or MinGW, so
maybe there's some weirdness on that front that escaped my notice.
