Re: [PATCH] R dependencies

[ludo@gnu.org (Ludovic Courtès)]

Now the closure of R is down from 5 GiB to 518 MiB, which is cool.  :-)

presumably unwanted dependencies being retained, such as Texinfo & Perl,
ld-wrapper & Binutils, Gawk and other build-time tools:

It Would Be Nice™ to identify where these references come from and
whether they can be discarded.
