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. > > regards, tom lane > 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. A Truly Happy Thanksgiving!
