The problem is that it returns the argument enclosed in parentheses:

cc: Warning: /home/lsd/oliva/src/egcs/gprof/gprof.c, line 59: In the initializer for copyright[0], "("@(#) Copyright (c) 1983 Regents of the University of California.

")" has a larger data size than "signed char".  Assignment may result in data loss.
 N_("@(#) Copyright (c) 1983 Regents of the University of California.\n\
-^

")" of type "pointer to signed char", is being converted to "signed char".

In fact, compiling:

char foo[] = ("bar");

fails similarly, but:

char foo[] = "bar";

works.
