Re: GNU libc snapshots work again on the Hurd
In libiberty/strerror.c(binutils,gdb), check program which tests
absense of sys_errlist returns
"undefined reference to `sys_errlist'"
So application undefines HAVE_SYS_ERRLIST or defines NEED_sys_errlist,
and defines application original symbol
#ifndef HAVE_SYS_ERRLIST
static int sys_nerr;
static const char **sys_errlist;
#else
But they conflict with stdio.h declarations that
#ifdef __USE_BSD
extern int sys_nerr;
extern const char *const sys_errlist[];
#endif
Although to use of sys_errlist is deprecated, sys_errlist &
_sys_errlist symbols shuould define again for consistency...
