Just factor out the common code into a seperate directory and use
OcamlMakefile to create a library out of it, for example:

kosha$ ls -F
CVS/            OcamlMakefile   erlang/         prog/
Makefile        doc/            lib/            sql/

kosha$ cat Makefile
SUBDIRS= lib prog/smtp_test prog/kosha

.PHONY: all
all:
        for dir in $(SUBDIRS); do (cd $$dir && $(MAKE)); done

.PHONY: clean
clean:
        for dir in $(SUBDIRS); do (cd $$dir && $(MAKE) clean); done


kosha$ cd lib
kosha/lib$ cat Makefile
#Note the two targets library dependencies for "all:"
OCAMLMAKEFILE=../OcamlMakefile

SOURCES=utils.ml mylist.ml mylist_test.ml io.ml
RESULT=klib
THREADS=yes

all:    debug-code-library native-code-library

LIBS=unix str netstring

-include $(OCAMLMAKEFILE)


kosha$ cd prog/kosha
kosha/prog/kosha$ cat Makefile
#Note well the two {LIB,INC}DIRS lines, and "klib" on the LIBS line
OCAMLMAKEFILE=../../OcamlMakefile

ocamlnet=ocnMisc.ml tokenize.ml mailmessage.ml

LIBDIRS += ../../lib
INCDIRS += ../../lib

SOURCES=$(ocamlnet) opt.ml match.ml db.ml canary.ml mailtype.ml\
        spamdb.ml mail.ml esmtp_parser.mly esmtp_lexer.mll\
        smtp_server.ml main.ml

RESULT=kosha
THREADS=yes

LIBS=unix str dbm pq netstring threads klib

all: dc

-include $(OCAMLMAKEFILE)
