Many of the complaints by the author are in the context of differences between C today and C back then, but back when CP/M was in common use, C compilers typically did not do much optimization, and K&R C was all there was. I did not use Aztec C until a few years after I switched from CP/M to DOS, but I really liked it, and used it for several 68k bare-metal projects. I did poke around with BDS C on CP/M, but was immediately turned off by the lack of standard floating point support. (It did offer an odd BCD float library.) https://www.bdsoft.com/dist/bdsc-guide.pdf https://www.bdsoft.com/dist/bdsc-guide.pdf
