[cfe-commits] [PATCH] Fix sigsetjmp builtin

[Dimitry Andric]

Hi,

The prototype for the built-in function sigsetjmp is incorrect, which
leads to warnings like (when compiling with -Wsystem-headers):

  In file included from ssjtest.c:1:
  /usr/include/setjmp.h:58:5: warning: incompatible redeclaration of library function 'sigsetjmp'
  int     sigsetjmp(sigjmp_buf, int);
	  ^
  /usr/include/setjmp.h:58:5: note: 'sigsetjmp' is a builtin with type 'int (struct _jmp_buf *, int)'

On both Linux and BSD the real prototype for sigsetjmp(3) actually is:

  int sigsetjmp(sigjmp_buf, int);

The attached patch corrects the LIBBUILTIN macro in Builtins.def.
