I hope you are not doing hello world in DllMain.
I suspect the problem is not in Vim but rather with Cygwin. So I
suggest to rectify your problem even further:
1) Create console win32 application which does NOT use Cygwin and uses
your library with LoadLibrary, GetProcAddress. Test whether this works
or not.

As I had a few minutes to spare and found this topic interesting I did what Sergey suggested above, and found that if the test application is compiled with -mno-cygwin then the LoadLibrary call never returns. So unless you want to investigate further _why_ LoadLibrary behaves this way you have 2 options: 1) Use the -mno-cygwin flag when building your .dll, this way you get a native win32 .dll. This of course also means that you won't have access to any of the POSIX emulation API provided by cygwin. 2) Use a cygwin-compiled version of vim (e.g. the one available via the cygwin-installer)
