While building the GNU ARM Embedded toolchain from the source invariant download, I noticed that pretty much the first thing to happen is downloading and unpacking of a bunch of additional source packages: gmp, mpfr, mpc, ISL, expat, etc.
Previous source distributions included all these packages or, at least, included their licence text in license.txt, which the q2 update does not.
What's the rationale for downloading these at build-time, rather than including them in the distribution, and what's the rationale for excluding them from license.txt?
Thanks,
steve
