With all the talk about crt0.c, locale and friends, I just saw the
following :
crt0.c:
if (getenv("ENABLE_STARTUP_LOCALE") != NULL)
_startup_setlocale(LC_ALL, "");
asm ("__callmain:"); /* Defined for the benefit of debuggers */
exit(main(kfp->kargc, argv, environ));
}
[...]
static char *
_getenv(name)
register char *name;
{
extern char **environ;
register int len;
register char **P, *C;
Why is it using "regular" getenv when it already has its own private one
_getenv ?
Note that changing getenv to _getenv does not really reduce binary
size. I've tried to recompile crt0.c without any *STARTUP* variables
defined to remove Andrey's "hack" and link "ls" static with it but "ls"
doesn't change.

-rwxr-xr-x 1 root wheel 167936 Oct 17 20:03 /usr/src/bin/ls/obj/ls*
That's probably expected, maybe I did not follow the proper procedure.
