+/* dllinit.c -- Portable DLL initialization. 
+   Copyright (C) 1998 Free Software Foundation, Inc.
+   Contributed by Mumit Khan (khan@xraylith.wisc.edu).
+
+   I've used DllMain as the DLL "main" since that's the most common 
+   usage. MSVC and Mingw32 both default to DllMain as the standard
+   callback from the linker entry point. Cygwin32 b19+ uses essentially 
+   the same, albeit slightly differently implemented, scheme. Please
+   see DECLARE_CYGWIN_DLL macro in <cygwin32/cygwin_dll.h> for more 
+   info on how Cygwin32 uses the callback function.
+
+   The real entry point is typically always defined by the runtime 
+   library, and usually never overridden by (casual) user. What you can 
+   override however is the callback routine that the entry point calls, 
+   and this file provides such a callback function, DllMain.
+
+   Mingw32: The default entry point for mingw32 is DllMainCRTStartup
+   which is defined in libmingw32.a This in turn calls DllMain which is
+   defined here. If not defined, there is a stub in libmingw32.a which
+   does nothing.
+
+   Cygwin32: The default entry point for cygwin32 b19 or newer is
+   __cygwin32_dll_entry which is defined in libcygwin.a. This in turn
+   calls the routine you supply to the DECLARE_CYGWIN_DLL (see below)
+   and, for this example, I've chose DllMain to be consistent with all
+   the other platforms.
+
+   MSVC: MSVC runtime calls DllMain, just like Mingw32.
+
+   Summary: If you need to do anything special in DllMain, just add it
+   here. Otherwise, the default setup should be just fine for 99%+ of
+   the time. I strongly suggest that you *not* change the entry point,
+   but rather change DllMain as appropriate.
