What does "word" mean here? Is it a 32-bit entity or is it according to
word_mode which is QImode for avr?

The latter, it is machine-dependent.

So the same should be true for QI-subregs of scalar modes if
UNITS_PER_WORT = 1. Right?

Right.

Thanks for that definite clarification.

Internals are sometimes confusing, incomplete or outdated, so I prefere to reassure me here. Thanks again :-)
