Hi Massimiliano,
>I'm using gcc 3.3.2 cross compiler for renesas h8s micros, and it doesn't work.
What does it do?
Can you drop in the offsetof macro?
#define offsetof(s_type,field) ((size_t)&(((s_type*)0)->field))
>In the official gcc docs it seems that offsetof (and __builtin_offsetof) is supported in version 3.5.0.
Then can you use GCC 3.5.0 (pre)?
HTH, --Eljay
