It's likely too many. Ld used to have lots of fixed sized arrays... I had to hack on the 2.10.1BSD to change supported ar formats and noticed. Also had to tweak some of the constants to get something much bigger compiling.  The BSD ld had overlay suppot merged into it, but was otherwise quite similar to V7, though I've not done a deep dive into ld from v7... 

Tl;dr: chances are good more, smaller files will work.

So maybe I missed a symbol when I was trying to make everything unique in 8 chars?  There are no external symbols; all that's in my forth.h are macros and typedefs.

I hate error messages like that.  Would it have been that much extra
trouble for ld to tell you which symbol caused the problem?

It's a relocation entry it can't find a symbol for that's the issue...
