gcc inlining

Hi devs,
in agg_basics.h file is declared macro AGG_INLINE that is used to heavy inline some larger functions. Under MSVC this is good, because it uses __forceinline keyword, but when I tried this with GCC and -Winline option enabled, I see that GCC not inlines pretty simple code. Soo, shouldn't be the AGG_INLINE definition changed to something like this? #if defined(_MSC_VER) #define AGG_INLINE __forceinline #elif defined(__GNUC__) #define AGG_INLINE inline __attribute__(always_inline) #else #define AGG_INLINE inline #endif I don't know if this affects performance a lot, I reccomend using -Winline to see what is not inlined Cheers - Petr ------------------------------------------------------------------------------ The NEW KODAK i700 Series Scanners deliver under ANY circumstances!
