From canonical sources, you rebuild the amalgamation by typing "nmake /f makefile.msc sqlite3.c". You'll need to install Tcl (http://tcl.tk/) for the build to work. The file you want to edit is "os_win.c". You can type "nmake /f makefile.msc test" to run a partial check of your changes. To be clear: the commands mentioned in the previous paragraph are run from within a "VS201X x64 Native Tools Command Prompt" window. If you come up with a patch that does improve performance, we would be interested in knowing what you did. But in order to preserve the "public domain" status of SQLite, we'll probably need to reimplement the change ourselves, from scratch. Either that, or we'll have to go round and round with your lawyers to get a public domain dedication out of them. Usually it's easier for us to just reimplement things ourselves here. -- D.
