I tried it on commit a69959fab2 just before the commit (1349d2790b)
which was causing problems for me. On running "perl mkvcbuild.pl", I
got the below error:
wrong number of input files, expected nodes/nodes.h nodes/primnodes.h
nodes/parsenodes.h nodes/pathnodes.h nodes/plannodes.h
nodes/execnodes.h access/amapi.h access/sdir.h access/tableam.h
access/tsmapi.h commands/event_trigger.h commands/trigger.h
executor/tuptable.h foreign/fdwapi.h nodes/extensible.h
nodes/lockoptions.h nodes/replnodes.h nodes/supportnodes.h
nodes/value.h utils/rel.h

This error seems to be originating from gen_node_support.pl. If I
changed the @node_headers to what it was instead of getting it from
Makefile then the patch works and the build is also successful. See
attached.
