Right.

Was it a symlink already? I thought I recalled it being a hard link or
a copy.

There might also be a dependency issue, ie does make realize that
updating backend/parser/parse.h means it has to recompile files
that are shown as depending on include/parser/parse.h. Offhand it
seems that this will fail to work unless backend/parser/Makefile
has a rule that makes the latter dependent on the former.
