Hm. They are. But: Still all variables are 32 bit aligned! And: Using gcc=
 2.95.2
under Linux or RiscOS I do not get this strange behaviour. Why does NetBS=
D
still use egcs?

One example structure looks like this:

#pragma pack(1)

struct test {
  int a,b;
};

#pragma pack()

If I now do access the content of this structure, the ints are accessed b=
y 4
LDRBs and 3 ORRs, which is absolutely not necessary.

Is there a chance that NetBSD/arm32 will soon use gcc 2.95.2?
