Hi,

I have legacy code using lvalue casting like this:
(unsigned long)a = b;
gcc-4.0.1 issues compilation error. Is there a compiler option to allow
this code?

Thanks,
    Yuri Karlsbrun

Hi Yuri,

Maybe the -fnon-lvalue-assign flag will do what you need.

But I think you should change the code to be compliant.

(type)expr           ---becomes--->  *(type *)&expr
cond ? expr1 : expr2 ---becomes--->  *(cond ? &expr1 : &expr2)

HTH,
