 LIBCHICKEN_SHARED_OBJECTS = library$(O) eval$(O) extras$(O)
 lolevel$(O) utils$(O) \
        tcp$(O) srfi-1$(O) srfi-4$(O) srfi-13$(O) srfi-14$(O) srfi-18$(O) \
        $(POSIXFILE)$(O) regex$(O) regex-extras$(O) scheduler$(O)
 profiler$(O) stub$(O) match$(O) \
         scheduler$(O) profiler$(O) stub$(O) match$(O) runtime$(O)

        ... Why be so verbose?  This could easily be rolled down to:

 LIBCHICKEN_SHARED_OBJECTS = patsubst(%, %$(O), library eval extras
 lolevel utils tcp srfi-1 srfi-4 srfi-13 srfi-14 srfi-18 $(POSIXFILE)
 regex regex-extras scheduler profiler stub match scheduler profiler
 stub match runtime)

        Likewise for LIBCHICKEN_STATIC_OBJECTS:

 LIBCHICKEN_STATIC_OBJECTS = patsubst(%, %-static$(O), library eval
 extras lolevel utils tcp srfi-1 srfi-4 srfi-13 srfi-14 srfi-18
 $(POSIXFILE) regex regex-extras scheduler profiler stub match runtime)

        Noticing a common sublist here, one could squeeze these two even
        further (not to a much surprise -- the source code for both
        static and dynamically-linked version of Chicken is the same):

 LIBCHICKEN_OBJECTS_1 = \
        library eval extras lolevel utils tcp srfi-1 srfi-4 srfi-13 \
        srfi-14 srfi-18 $(POSIXFILE) regex regex-extras scheduler \
        profiler stub match
 LIBCHICKEN_SHARED_OBJECTS = \
        patsubst(%, %$(O), $(LIBCHICKEN_OBJECTS_1) scheduler profiler
 stub match runtime)
 LIBCHICKEN_STATIC_OBJECTS = \
        patsubst(%, %-static$(O), $(LIBCHICKEN_OBJECTS_1) runtime)

        If the duplicate entries aren't really necessary in
        LIBCHICKEN_SHARED_OBJECTS (and, I guess, it's the case), it
        shortens down to this, much more concise notation:

 LIBCHICKEN_OBJECTS_1 = \
        library eval extras lolevel utils tcp srfi-1 srfi-4 srfi-13 \
        srfi-14 srfi-18 $(POSIXFILE) regex regex-extras scheduler \
        profiler stub match runtime
 LIBCHICKEN_SHARED_OBJECTS = \
        patsubst(%, %$(O), $(LIBCHICKEN_OBJECTS_1))
 LIBCHICKEN_STATIC_OBJECTS = \
        patsubst(%, %-static$(O), $(LIBCHICKEN_OBJECTS_1))

        Performing this kind of optimization through the rules.make, the
        following could be obtained:

        library eval extras lolevel utils tcp srfi-1 srfi-4 srfi-13 \

 LIBUCHICKEN_STATIC_OBJECTS = $(LIBUCHICKEN_OBJECTS_1:=-static$(O))
