[Bug bootstrap/44305] New: warning: cast discards qualifiers from pointer target type -- -disable-bootstrap should not use -Wcast-qual

warning: cast discards qualifiers from pointer target type

There are at lot of these building gcc.
Including but not limited to:

../../gcc-4.5/gcc/gimple.h: In function ‘gimple_op’:
../../gcc-4.5/gcc/gimple.h:1635: warning: cast discards qualifiers from pointer
target type
../../gcc-4.5/gcc/gimple.h: In function ‘gimple_op_ptr’:
../../gcc-4.5/gcc/gimple.h:1651: warning: cast discards qualifiers from pointer
target type


Yes, I realize it is dependent on host compiler (Apple gcc 4.0.1 in my case)
and that I'm using -disable-bootstrap.

I would suggest -disable-bootstrap should not pass -Wcast-qual, and that
"regular" should not pass it in the first pass.

Unless there is another way, like __extension__ or _Pragma or #pragma GCC can
quash it on known places.
