lark:~$g++ -v
Using builtin specs.

>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
