that patch won't work. int foo[]; allocates the array at the end of the structure, int *foo; creates a pointer to memory somewhere else.

A better patch would be to replace int foo[]; with int foo[0]; if gcc-2.95 would let you (from my vague memory it does), or int foo[1]; and check for things that use sizeof(outerstruct) as the size of the struct will now be wrong.

"In ISO C90, you would have to give contents (bar in my example) a length of 1, which means either you waste space or complicate the argument to malloc."

Does this mean hat if I use int bar[1] and I do'nt mind to waste space, I do not have to change any sizeof() arguments?

Another question: how do I check for gcc < 3 ?

06/07/07 15:45:01 changed by anonymous

gcc-2.95 accepts 'int foo[0];' - it does exactly the same as 'int foo[];'. It works very well on my Linux based ADSL modem/wireless AP :-). I attached a new patch. No need to check for gcc < 3. Please apply ;-).
