Huh ... do you recall the details? Large as tab-complete is, it's far smaller than gram.y: ...
So I'm having a hard time guessing why we'd hit compiler limits in tab-complete if we can build the rest of the system.

Oh, I hit them. In the tab-complete.c you have a SINGLE if/else that spans over 2,000 lines.
And it blows up the STACK of the C Compiler (stack overflow). (It took 1 variable (if_continues)) and ENDING the if, and restarting it.
Also, the PREPROCESSOR you need the flag: "Use Standard Conforming Processor" (or V_ARGS and NARGS breaks).
[ (/Zc:preprocessor) ]
of course SOMEONE should ask WHY use a non-conforming pre-processor??? It cost me hours...
Currently I have a lot of it working, but I need to partner up with some of the meson guys...
if it is already close to working, a couple of my tweaks could accelerate it.
