+Subject: [PATCH xserver] Use spawnl() rather than pipe() & fork() to invoke
+ xkbcomp
+
+Implement System() specially on Cygwin not to use fork() and exec(), but
+spawnl()
+
+Use System() and a temp file rather than pipe() & fork() to invoke xkbcomp on
+cygwin, just as done on mingw
+
+Somewhat the counsel of despair, but sometimes Windows is being such a little
+bitch that the cygwin DLL just can't emulate fork() successfully, so just using
+spawnl() here is more robust and means I don't have to deal with end-users
+reporting this as a problem with the xserver
+
+Popen is not used, but must be built as it is referenced by sdksyms
+
+v2: Update to include fix to Win32TempDir() when TMP is set but TEMP isn't
+
+XXX: Really this should check TMPDIR first, as that's the canonical UNIX way to
+set the temporary directory?
+
+v3: Fix implicit-function-declaration of Win32TempDir() in XkbDDXCompileKeymapByNames()
+
+Add a prototype for Win32TempDir()
+
+v4: Improve handling of error conditions with the xkbcomp temporary file
+
+Fix a compilation conditional so that a failure to write to the xkbcomp
+temporary file is correctly reported, and reports the problematic filename.
+
+Improve Win32TempDir() so that the directory given by the TEMP and TMP
+environment variables is checked for accessibility, so that specifying a
+non-existent directory doesn't cause a failure.
