Only that I asked on comp.std.c and was told point blank that escapes
were to be interpreted.  See <I0J8sxlaKtP8EwiY@romana.davros.org> and
my response to same.

I don't think it makes a hell of a lot of sense for escapes to be
interpreted in #line, although I _can_ make a case depending on the
premise that #line will usually appear in machine-generated code.
