http://cygwin.com/faq/faq.html#TOC102 Note that this just references loading cygwin1.dll and getting it initialized. If you have your own DLL that depends on cygwin1.dll you will probably first have to load and initialize Cygwin, and then load your own DLL. You may still run into issues if you are trying to use both MSVCRT*.dll and Cygwin in the same application. They both implement a completely separate and incompatible C runtime library, and it certainly won't work if you try to include both at link-time. You might get around the issues if you load cygwin1.dll dynamically and do everything through GetProcAddress, since that takes care of the problem of having duplicate symbols for all the CRT functions. In your example that would mean calling GetProcAddress for the address of strcpy (and any other Cygwin function you plan to use.) And, as far as I know, using cygwin1.dll in this way means all your code must be released under the GPL, or another OSI approved license.
