Sure. Did you read the whole message?

It's not really that different! Firstly I expand only bin/ to
bin/gcc-N.N-N. Then, for 4.2.3, I only expand lib/ and libexec/, because
I don't need gnu/, info/, ... for every single version. For 4.3.2, e.g.,
the latest version, I also want gnu/, info/, ... for reference. So I
expand everything except bin/ with the second call.

I think, you just didn't understand, what I did.

I also do already for years.

Not very new.

"more"? "*MUCH* more"! Around 100M for a typical installation. 2 DJGPPs
x 6 GCCs x 100M = 1.2G just for DJGPP?! No, thanks!
