Makefile.am:
# The Automake generated .y.c rule is broken: When executed in a VPATH build,
# - The .c file gets generated in the build directory. But since it requires
# special tools to rebuild it, we need to distribute it in the tarballs,
# and by the GNU Coding Standards
# <https://www.gnu.org/prep/standards/html_node/Makefile-Basics.html>
# the file should be generated in the source directory.
# - The #line directives in the .c file refer to a nonexistent file once it
# has been moved from the build directory to the source directory. This
# leads to error if 'lcov' is used later.
# Additionally, here we assume GNU Bison and therefore don't need the ylwrap
# script.
# Therefore we override this rule.
# Since this is a rule that produces multiple files, we apply the idiom from
# <https://lists.gnu.org/archive/html/bug-make/2020-09/msg00008.html>, so that
# it works also in parallel 'make'.
