The INSTALL file says that DCMTK can be compiled using the Cygwin development environment for Windows. However, Step 1 of the install instructions does not work because the configure script fails completely (it reports "permission denied" problems and generates strange files in all the sub-directories).
You need to make sure that your PATH environment variable is set up so that the Cygwin tools directory will be searched before the standard Windows locations (e.g. \WINDOWS\..) when when executing a program. The main problem is that the DCMTK configure scripts use the Unix-like "find" program whereas Windows has its own, incompatible, "find" program. Unless you arrange otherwise, the wrong "find" program will be used.
