The problem in that link is stated like this:

  lstate.h uses TM_N from ltm.h and lstate.h uses nothing from ltm.h

Maybe I am missing something, but that statement seems slightly
contradictory.

Hi Roberto,

Good point, well made. ltm.h uses nothing from lstate.h. 

What I actually did after seeing the circular include was delete one, notice the build break, then delete the other and see that the build & test was fine. Then actually check the contents of the headers and the order in which they're included in various files.

Cheers!
