Keep in mind that there are two possible OS environments we are dealing + with -- Cygwin and Native Windows. Cygwin provides a POSIX emulation + layer on top of MS Windows -- in particular, providing the file-system, + process, tty, and signal semantics that are part of a modern, standard + Unix operating system. MS Windows also provides these services, but + through their own API, called Win32. When compiling in a Cygwin + environment, the Win32 API's are also available, and in fact are used + to do native GUI programming. + +2. There are two windowing environments we can target XEmacs for when + running under MS Windows -- Windows native, and X. (It may seem strange + to write an X application under Windows, but there are in fact many X + servers out there running on Windows, and as far as I know there is no + real (or at least, that works well) networking Window-system extension + under MS Windows. Furthermore, if you're porting a Unix application to + Windows and use Cygwin to assist you, it might seem natural to use an + X server to avoid having to port all the code to Windows.) For XEmacs, + there are various reasons people could come up with for why we would + want to keep maintaining X Windows under MS Windows support. + +That gives us four possible build environments. I (Ben) build +regularly on fully-native-everything, Andy builds on Cygwin + MS +Windows + X Windows for windowing. + +The build flags used for these divisions are: + +CYGWIN -- for Cygwin-only stuff. +WIN32_NATIVE -- Win32 native OS-level stuff (files, process, etc.). +HAVE_X_WINDOWS -- for X Windows (regardless of whether under MS Win) +HAVE_MS_WINDOWS -- MS Windows native windowing system (anything related to + the appearance of the graphical screen). + +Finally, there's also the MINGW build environment, which uses GCC +\(similar to Cygwin), but native MS Windows libraries rather than a +POSIX emulation layer (the Cygwin approach). This environment defines +WIN32_NATIVE, but also defines MINGW, which is used mostly because +uses its own include files (related to Cygwin), which have a few +things messed up. + + +Formerly, we had a whole host of flags.
