Maybe we could all this into a wrapper? If getenv() here has a
problem, many other places may have the same problem too. This
simplifies the change. But one has to check that getenv() must not be
used in threaded code.
char *git_getenv(const char *env)
{
static int bufno;
static char *buf[4];
bufno = (bufno + 1) % 4;
free(buf[bufno]);
buf[bufno] = xstrdup(getenv(env));
return buf[bufno];
}
#define getenv(x) git_getenv(x)
