Why would it be an error? EGCS doesn't usually give an error unless it
absolutely has to. It lets you change const variable's with only a
warning*. While negative line numbers may be unusual, and against the
ISO standard, there's no reason to offer an error unless the compiler
can't handle it. And if it can't handle it, it may not be necessary to
offer a warning if it can work around it.

* Not that I entirely agree with this, but it does appear to be the
GCC/EGCS way.
