# These rules are used if someone wants to rebuild ncgenl.c or ncgeny.c
# Otherwise never invoked, but records how to do it.
# BTW: note that renaming is essential because otherwise
# autoconf will forcibly delete files of the name *.tab.*
# Note also that this should be built under linux or cygwin
# using bison version 3 or later.
# Note also that this code is in a shell script if you do
# not want to other to ./configure.
