Looks like breakage of the ELF __IDSTRING macro.

#if defined(__GNUC__) && defined(__ELF__)
#define __IDSTRING(name,string) __asm__(".ident\t\"" string "\"")
#else
#define __IDSTRING(name,string) static const char name[] __unused = string
#endif

This seems to work:

#define __IDSTRING(name,string) __asm__(".ident\t" #string)
#define __COPYRIGHT(s)  __IDSTRING(copyright,s)

__COPYRIGHT("@(#) Copyright (c) 1983, 1988, 1993\n"
            "The Regents of the University of California."
            "  All rights reserved.\n");

int
main(void)
{

        exit(0);
}
