I guess that characterization surprises me. The man page for
getopt_long() says this, and has for a long time at least on systems
I've used:
ENVIRONMENT
POSIXLY_CORRECT If set, option processing stops when the first non-
option is found and a leading `-' or `+' in the
optstring is ignored.
And also this:
BUGS
The argv argument is not really const as its elements may be permuted
(unless POSIXLY_CORRECT is set).
Doesn't that make it pretty clear what the GNU version is doing?
