Variable: c-indent-comments-syntactically-p

c-indent-comments-syntactically-p is a customizable and buffer-local variable defined in cc-vars.el.gz.

Documentation

Specifies how M-x indent-for-comment (indent-for-comment) should handle comment-only lines.

When this variable is non-nil, comment-only lines are indented according to syntactic analysis via c-offsets-alist. Otherwise, the comment is indented as if it was preceded by code. Note that this variable does not affect how the normal line indentation treats comment-only lines.

This is a style variable. Apart from the valid values described above, it can be set to the symbol set-from-style. In that case, it takes its value from the style system (see c-default-style and c-style-alist) when a CC Mode buffer is initialized. Otherwise, the value set here overrides the style system (there is a variable c-old-style-variable-behavior that changes this, though).
