Comment (by kencu):

 I have been building TenFourFox since 2018. One of the other regulars
 around here, Riccardo, and I sorted out the patches to make it build as
 Intel on a Tiger i386 machine over the Christmas holidays back then. I
 find it is very simple to build, but takes time.

 I wrote up a Portfile to automatically build it for MacPorts
 <https://github.com/kencu/tenfourfox-macports>, but -- it was a big huge 6
 hour build and in the end I just built it every time there was a new
 version and uploaded it to the TenFourFox sourceforge repo.

 Here's how I build it on Intel from their default github repo:

 <https://github.com/kencu/tenfourfox/blob/FPR32branch/HOWTOBUILD>

 Building it on 10.5 PPC is a bit easier because you don't need clang-3.4
 and yasm, or any patches.

 I didn't know about that thread you referenced. Perhaps I will answer some
 of the questions in there. I use gcc7/libgc7 7.4.0 still because gcc7
 7.5.0 introduced a new bug that makes a lot of software crash. It's a bit
 technical to explain but it has to do with an interaction between the
 system libstdc++ and the one installed by libgcc 7.5.0. Upstream thinks
 they have a fix for this that might work.
