+/* 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.
