conflicts due to radically different approaches to security and bug fixes. In some cases I re-started from the vendor version and reimplemented our patches. Fortunately, this is not enabled by default in -current.

If the caller did not specify anything,

the default is REQUIRE_ORDER if the environment variable
|

POSIXLY_CORRECT is defined, PERMUTE otherwise.
|
||
|
||
REQUIRE_ORDER means don't recognize them as options;
|
||
stop option processing when the first non-option is seen.
|
||
This is what Unix does.
|
||
This mode of operation is selected by either setting the environment
|
||
variable POSIXLY_CORRECT, or using `+' as the first character
|
||
of the list of option characters, or by calling getopt.
|
||
|
||
PERMUTE is the default. We permute the contents of ARGV as we
|
||
scan, so that eventually all the non-options are at the end.
|
||
This allows options to be given in any order, even with programs
|
||
that were not written to expect this.
|
||
|
||
RETURN_IN_ORDER is an option available to programs that were
|
||
written to expect options and other ARGV-elements in any order
|
||
and that care about the ordering of the two. We describe each
|
||
non-option ARGV-element as if it were the argument of an option
|
||
with character code 1. Using `-' as the first character of the
|
||
list of option characters selects this mode of operation.
|
||
|
||
The special argument `--' forces an end of option-scanning regardless
|
||
of the value of `ordering'. In the case of RETURN_IN_ORDER, only
|
||
`--' can cause `getopt' to return -1 with `optind' != ARGC. */
