I suppose in a GNU only world, this would be okay. However, my man page for
ar still says:
-u
Copies only files that have been changed since they were last
copied (see the -r flag discussed previously).
while the option -D is not found.
root@x065:[/data/prj/python/python-2.7.8.2]ar -D
Usage: ar [-X{32|64|32_64|d64|any}] [-clsvCT] [-g|o] {-h|p|t|x}
[--] Archive [File ...]
ar [-X{32|64|32_64|d64|any}] [-clsvCT] [-g|o] {-m|r[u]}
[{-a|b|i} {PositionName}] [--] Archive File ...
ar [-X{32|64|32_64|d64|any}] [-clsvCT] [-g|o] {-d|q}
[--] Archive File ...
ar [-X{32|64|32_64|d64|any}] [-clvCT] {-g|o|s|w} [--] Archive
so, I think adding -D as a default will break "all" for me.
If the patch differentiates between GNU environment and Not GNU - then
nothing said. But, "things" which have been the standard for 10's of years
should not be changed suddenly (why change at all if it is all scripted? I
am not looking for more job security - I prefer productivity :smile: )
