lark:~$g++ -v
Using builtin specs.
gcc version 2.95.2 19991024 (release)
lark:~$

>Description:

	C++ does not like tagless symbols

>How-To-Repeat:

sample program:
--- cut here ---
#include <setjmp.h>

int
foo(jmp_buf *j)
{
}
--- cut here ---

lark:~$g++ -c foo.cc
foo.cc:4: non-local function `int foo({anonymous struct} (*)[1])' uses anonymous type
lark:~$

>Fix:

*** setjmp.h.orig	Tue Jan 18 14:52:29 2000
--- setjmp.h	Tue Jan 18 14:51:53 2000
***************
*** 40,46 ****
