17 # This test checks that dependent files are updated before including
18 # in the distribution. 'parse.c' depends on 'parse.y'. The later is
19 # updated so that 'parse.c' should be rebuild. Then we are running
20 # 'make' and 'make distdir' and check whether the version of 'parse.c'
21 # to be distributed is up to date.
23 # Please keep this in sync with sister test 'yacc-d-vpath.sh'.
