__COPYRIGHT is defined as
#define __COPYRIGHT(s) __IDSTRING(copyright,s)
and __IDSTRING is
#define __IDSTRING(name,string) __asm__(".ident\t\"" string "\"")
By the time the string makes it to the assembler, the \n's have been
turned into (real) NL's so the assembler line looks like
.ident "@(#) Copyright (c) 1983, 1988, 1993
The Regents of the University of California. All rights reserved.
"
...and it does not like the multi-line string. You may need to
double-escape the \n's (like \\n) to get them into the .ident
line symbolically.
(I just checked - it worked!)
