I'm trying to read the gcc info manual on emacs, without download the entire source of gcc. In particular, I've downloaded tarballs at https://gcc.gnu.org/onlinedocs/ under "texinfo sources of all the gcc 8.3.0" manuals. However, it is completely unclear what to do with these. Naively attempting to do `texinfo gcc.texi` fails, complaining about missing files like `gcc-common.texi`, even though they are easily found in a nearby `include` directory. The issue seems to be that since the standalone texinfo source tarball doesn't contain any Makefiles, the set of manuals cannot be built. Am I missing something obvious here?
