Yes. 

Why is this surprising? You are building a compiler from sources; part
of the sources for that compiler is gcc 2.8.1.

Getting hold of the source for gcc 2.8.1 is no harder than getting
hold of the source for gnat 3.13p.

Perhaps you are implying that the source distribution for gnat 3.13p
should include the source distribution of gcc 2.8.1. That might be
convenient for you, but it is common practice to simply reference an
independent source distribution, when that imposes no significant
burden on the user.

Yes. It would be better if this specific instruction were in the
README file, but a quick read of patch --help makes it pretty clear.
In general, it is assumed people installing from source can figure out
how to use the required tools.
