[C++ Patch] PR 26155 (improved patch)

Hi, this is my last and best try ;) Seriously, compared to the last posted version: 1- I added a rather large comment explaining what's going on wrt error recovery. 2- Took the occasion to clean-up a bit the code about bool vs int for flags (we had a mix). 3- Cleaned-up a bit the code itself
