You have to add the following to src/Makefile.am,
since with your change, df and stat are no longer derived
solely from df.c and stat.c respectively:

df_SOURCES = stat.c find-mount-point.c
stat_SOURCES = df.c find-mount-point.c

Note that I didn't even review (more than superficially)
or test your patch.  If you have to make any change at all
when moving the function from df.c to the new file, please
tell us about it.  Otherwise, the function body in the new file
should be identical.
