Linux should define ENOTSUP

Hi,

ENOTSUP is not used at all by linux (though it is defined for parisc),
while as susv3 specifies, ENOTSUP shall be different than EOPNOTSUPP.
Is there a reason for doing so? (except history)

Currently, code like

switch(errno) {
ENOTSUP:
foo();
break;
EOPNOTSUP:
bar();
break;
}
just can't compile...

Is there any way to fix this? Glibc people don't seem to want to fix it
on their part, see
