From e267505d5472e8c3150ad1cd197d11c955e316c6 Mon Sep 17 00:00:00 2001 From: Mark Brand Date: Fri, 16 Jan 2015 19:25:23 +0100 Subject: update bundled sqlite to 3.8.8.1 The "Fixed CE build of sqlite3" patch is preserved in this change, which causes sqlite's own localtime implementation to be used for wince. This is extended by #undef HAVE_LOCALTIME_S to override the new assumption that localtime_s is available on wince and should be used. Also, removed HAVE_LOCALTIME_S=0 since this must now be undefined instead of 0.
