Hi Boris,

yes I know, but "-O2 -fno-strict-aliasing" should be supported, if I 
understand correctly. According to gcc manual -Os is the same as -O2 but 
without the optimizations known to produce large memory footprint. I 
also tested -Os -fno-strict-aliasing and it shows the same behavior. I 
am also happy with just using -O(1), just wanted to let someone know 
that 7.0 works different for me than 6.2


Kind Regards,

Jan
