 As for now, only the Microsoft compiler and tools are really

+When using the cygwin compiler and tools *with* the cygwin runtime the
+normal Unix configuration method should work as if on Unix (knock on
+wood).
+
+With a little work, it might be possible to use the ./configure
+mechanism also with a "mingw32" configuration. I.e. building GLib for
+Win32 would use the cygwin tools (and dll), but the produced libraries
+would not depend on the cygwin runtime being present.
+
+The following preprocessor macros are used for conditional compilation 
+related to Win32:
+
+- WIN32 is defined when compiling for the Win32 platform, regardless
+  if using the X11 or Win32 GUI API (of course, in the case of GLib, this
+  dimension isn't significant), regardless whether using a more
+  or less complete Unix emulation runtime layer (like Cygwin) or not.
+
+- NATIVE_WIN32 is defined when compiling for Win32, *and* without
+  any Unix emulation, other that to the extent provided by the
+  (Microsoft) C library, or the pthreads-win32 library. For instance,
+  pathnames use the native Windows syntax.
+
+- _MSC_VER is defined when using the Microsoft compiler.
+
+Currently the Win32 port uses the combination with all three of those
+on, but eventually the cygwin compiler and tools will be supported
+also, and in that case _MSC_VER wouldn't be defined.
+
+Some of the usage of these macros is probably a bit mixed up, and will
+have to be straightened out when actually trying other combinations.
+
+The thread support uses the pthreads for Win32 package available from
+http://sourceware.cygnus.com/pthreads-win32/, which isn't ready yet,
+and thus really should not be relied upon.
