Summary: make fails to interpret src/backend/storage/Makefile correctly

System Configuration
--------------------
Operating System : Digital Unix 4.0D

PostgreSQL version : 6.4.2

Compiler used : gcc 2.8.0

Hardware:
---------
OSF1 erdos V4.0 878 alpha

Versions of other tools:
------------------------
gmake 3.76.1
flex 2.5.4

--------------------------------------------------------------------------

Problem Description:
--------------------
The build fails with messages like
for i in buffer file ipc large_object lmgr page smgr; do gmake -C $i buffer/SUBS
YS.o; done
gmake[3]: Entering directory `/usr/local/src/postgresql-6.4.2/src/backend/storag
e/buffer'
gmake[3]: *** No rule to make target `buffer/SUBSYS.o'. Stop.
gmake[3]: Leaving directory `/usr/local/src/postgresql-6.4.2/src/backend/storage
/buffer'

These messages are generated for all the subdirectories in the list.
They are produced from the target:
.DEFAULT:
for i in $(DIRS); do $(MAKE) -C $$i $@; done

Evidently $@ is getting expanded to $$i/SUBSYS.o instead of SUBSYS.o.

--------------------------------------------------------------------------

Test Case:
----------

--------------------------------------------------------------------------

Solution:
---------
My fix was to add specific targets buffer/SUBSYS.o et al
to the file src/backend/storage/Makefile. For example, add:

buffer/SUBSYS.o:
$(MAKE) -C buffer SUBSYS.o

This was repeated with ``buffer'' replaced by each of the dirs
in turn.
