This is not reproducible, but here's the report anyway:

I upgraded a Windows 10 system from Cygwin 3.5.3 to 3.5.5 today.
Then ran the configure script of a tarball (*), and it hung:

$ mkdir build-cygwin64
$ cd build-cygwin64
$ ../configure --host=x86_64-pc-cygwin --prefix=/usr/local/cygwin64 CC=x86_64-pc-cygwin-gcc CXX=x86_64-pc-cygwin-g++ CPPFLAGS="-I/usr/local/cygwin64/include -Wall" LDFLAGS=-L/usr/local/cygwin64/lib -C --with-included-libunistring 2>&1 | tee log1

Typing Ctrl-C in said mintty window has no effect.
