Many of these are likely harmless or trivial in nature, however some of them are potentially serious SEGV material, so all of them should be investigated and fixed for X11R7. bitscale.c:1843: warning: 'isStringProp' may be used uninitialized in this function file.c:69: warning: unused variable 'left' file.c:124: warning: suggest parentheses around assignment used as truth value fonts.c:2401: warning: missing braces around initializer fonts.c:2401: warning: (near initialization for 'builtin_files[0]') fonts.c:2410: warning: missing braces around initializer fonts.c:2410: warning: (near initialization for 'builtin_dir[0]') fonts.c:2428: warning: missing braces around initializer fonts.c:2428: warning: (near initialization for 'builtin_alias[0]') fpe.c:51: warning: implicit declaration of function 'BuiltinReadDirectory' fpe.c:51: warning: nested extern declaration of 'BuiltinReadDirectory' fpe.c:80: warning: no previous prototype for 'BuiltinRegisterFpeFunctions' fpe.c:81: warning: implicit declaration of function 'BuiltinRegisterFontFileFunctions' fpe.c:81: warning: nested extern declaration of 'BuiltinRegisterFontFileFunctions' render.c:35: warning: return type defaults to 'int' render.c:64: warning: implicit declaration of function 'CheckFSFormat' render.c:64: warning: nested extern declaration of 'CheckFSFormat' render.c:71: warning: implicit declaration of function 'pcfReadFont' render.c:71: warning: nested extern declaration of 'pcfReadFont' render.c:45: warning: unused variable 'i' render.c:82: warning: return type defaults to 'int' render.c:95: warning: implicit declaration of function 'pcfReadFontInfo' render.c:95: warning: nested extern declaration of 'pcfReadFontInfo' render.c:90: warning: unused variable 'renderer' render.c:88: warning: unused variable 'i' render.c:101: warning: missing braces around initializer render.c:101: warning: (near initialization for 'renderers[0]') render.c:109: warning: no previous prototype for 'BuiltinRegisterFontFileFunctions' fserve.c:2782: warning: 'ret' may be used uninitialized in this function paths.c:1039: warning: 'mypoint.x' is used uninitialized in this function paths.c:1040: warning: 'mypoint.y' is used uninitialized in this function t1info.c:1057: warning: 'sDescent' may be used uninitialized in this function t1info.c:1057: warning: 'sAscent' may be used uninitialized in this function
Mostly trivial stuff not worth tracking. The best way for handling these types of issues is to organize a community project upstream to get the whole tree of Xorg building warning-free on Linux and possibly on BSD and/or Solaris in the future.
