>Description:
The definition in machine/setjmp.h for i386 is:
typedef struct { int _sjb[_JBLEN + 1]; } sigjmp_buf[1];
typedef struct { int _jb[_JBLEN + 1]; } jmp_buf[1];
g++ complains when it cannot resolve the name of the structure.
>How-To-Repeat:
The following C++ program:
#include <setjmp.h>
sigjmp_buf& foo();
produces the following message:
foo.cc:3: non-local function `struct {anonymous} (& foo())[1]' uses anonymous ty
pe
>Fix:
typedef struct _sigjmp_buf { int _sjb[_JBLEN + 1]; } sigjmp_buf[1];
typedef struct _jmp_buf { int _jb[_JBLEN + 1]; } jmp_buf[1];
