GNU autoconf's unsetenv test fails on 9.1 - see test case below.
>Description:
>How-To-Repeat:
The autoconf test is reproduced below - the 'return 3' is the failing line
#include <stdlib.h>
#include <errno.h>
extern char **environ;
int main(int argc, char *argv[])
{
char entry1[] = "a=1";
char entry2[] = "b=2";
char *env[] = { entry1, entry2, NULL };
if (putenv ((char *) "a=1")) return 1;
if (putenv (entry2)) return 2;
entry2[0] = 'a';
unsetenv ("a");
if (getenv ("a")) return 3;
if (!unsetenv ("") || errno != EINVAL) return 4;
entry2[0] = 'b';
environ = env;
if (!getenv ("a")) return 5;
entry2[0] = 'a';
unsetenv ("a");
if (getenv ("a")) return 6;
return 0;
