It is not possible currently. execl* are specified by POSIX as returning int, so ... > I see two different approaches for this: > a) Add in builtin-types.h a '#if defined(TARGET_64BIT_MS_ABI) && > TARGET_64BIT_MS_ABI != 0' to add a specific function type and use in > bultins.def this function type. > b) Add in target mingw and new macro specifying the return type for > builtins. Add to default.h the standard value and add in builtin-types.def > the function type and use it in builtin.def c) Supressing this builtin on mingw64 ... should be the correct thing. For example with (builtins.def) #if defined(TARGET_64BIT_MS_ABI) && TARGET_64BIT_MS_ABI != 0' #define DEF_EXT_LIB_BUILTIN_NO_MINGW(....) #else #define DEF_EXT_LIB_BUILTIN_NO_MINGW(....) DEF_EXT_LIB_BUILTIN(...) #endif and change the offending builtins to use DEF_EXT_LIB_BUILTIN_NO_MINGW Richard.
