While this works with mainline Automake (which blindly treats source
files with an unknown extension as if they were header files), it is

such feature would make a port to Automake-NG more difficult.
* libparted/labels/Makefile.am (liblabels_la_SOURCES): ... don't

(EXTRA_DIST): ... list 'pt-limit.c' and 'pt-limit.gperf' here.
(EXTRA_DIST, BUILT_SOURCES): Enhance few comments.
