From b0a642ac4624740187212aecec62b35a2eab38cb Mon Sep 17 00:00:00 2001 From: Ramsay Jones Date: Mon, 8 May 2017 21:45:56 +0100 Subject: git_fopen: fix a sparse 'not declared' warning If git is built with the FREAD_READS_DIRECTORIES build variable set, this would cause sparse to issue a 'not declared, should it be static?' warning on Linux. This is a result of the method employed by 'compat/fopen.c' to suppress the (possible) redefinition of the (system) fopen macro, which also removes the extern declaration of the git_fopen function. In order to suppress the warning, introduce a new macro to suppress the definition (or possibly the re-definition) of the fopen symbol as a macro override. This new macro (SUPPRESS_FOPEN_REDEFINITION) is only defined in 'compat/fopen.c', just prior to the inclusion of the 'git-compat-util.h' header file.
