However, AUTOCHDIR is listed as a "feature" in feature.h so I would think it
should included in feature-list and therefore should be recognized by has() and
:version. Why should some "features" be recognized and not others?

My experience is different. Here's the full disclosure.
I always build Vim under Windows using mingw and specify FEATURES=NORMAL. I
wanted to have the 'autochdir' feature but did not want to build with BIG
features because I have no use for 'rightleft', 'farsi', and others. So I
added -DFEAT_AUTOCHDIR to the make variable DEFINES in Make_cyg_ming.mak. I
was able to build without error and all tests passed. To make sure that the
'autochdir' feature was included, I tried has() and :version and saw that it
was not listed. An investigation into why then lead to my proposed patches.
