From 657b35f4bef7d25831607882ed7f1f2ced378eb7 Mon Sep 17 00:00:00 2001 From: Ramsay Jones Date: Sat, 27 Apr 2013 20:18:55 +0100 Subject: [PATCH] compat/mingw.c: Fix some sparse warnings Sparse issues the following warnings: SP compat/mingw.c compat/mingw.c:795:3: warning: symbol 'pinfo_t' was not declared. \ Should it be static? compat/mingw.c:796:16: warning: symbol 'pinfo' was not declared. \ Should it be static? compat/mingw.c:797:18: warning: symbol 'pinfo_cs' was not declared. \ Should it be static? compat/mingw.c:1207:23: warning: Using plain integer as NULL pointer In 'pinfo_t' variable, defined on line 795, seems to have been a mistake (a missing typedef keyword?), so we simply remove it. The 'pinfo' variable does not require more than file scope, so we simply add the static modifier to the declaration. The 'pinfo_cs' variable, in contrast, requires initialisation in the mingw replacement main() function, so we add an extern declaration to the compat/mingw.h header file. The remaining warning is suppressed by replacing the rhs of the pointer assignment with the NULL pointer literal.
