From c4642788e83b0858bca449f9b6e71ddb015dfa5d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Martin=20Storsj=C3=B6?= Date: Wed, 10 Apr 2019 11:39:01 +0300 Subject: [PATCH] time_internal: Prefix fallback versions of gmtime_r/localtime_r with ff_ MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Use a macro to redirect calling code from the official name to the ff_ prefixed one. Detecting these functions in configure can be tricky (on mingw, they are conditionally available depending on posix feature defines). If configure didn't detect them, but they still are visible at compile time (due to an unrelated header defining the posix feature defines), providing the local fallback versions with a prefixed name is safer.
