Hi,

I notice about 20% speed regression with GCC 4.4.0 PNGCrush build compared to 
GCC 3.4.0 build (Amiga 68...@50mhz). 

CFLAGS = -I. -DNO_FSEEKO -O2 -fomit-frame-pointer -Wall -m68060 -s

Here are the results:

GCC 3.4.0:

CPU time used = 267.340 seconds (decoding 16.940,
encoding 247.800, other 2.600 seconds)

GCC 4.4.0:

CPU time used = 328.360 seconds (decoding 16.800,
encoding 309.260, other 2.300 seconds) 

Maybe someone with m68k Debian/PPC/x86 can compile PNGCrush with GCC 3.4.0 and 
GCC 4.4.0, so we will know if this regression happens there too?

Regards
