   After the obvious suggestion to search the net for a 
   paper titled "Recursive Make Considered Harmful", i
   have a few feelings:

1. Check your makefile. Most probably you are using a shell script 
   like this
all: for x in $DIRS\
      (cd $x ; make)

    This will of course not work, since lowerlevel's make's retgurn
    code is being ignored.
    Instead try something like this:
     (cd $x ; make ; if $? != 0 exit 1 )
    (suit to your particular /bin/sh )

2. something like this
   i write a macro to have each directory in $DIRS with a _dir extension
  ( e.g. (src lib) ==> (src_dir lib_dir)
   And have rule such as
all_dir:  $(DIRS_dir)

$(DIRS_dir):
      cd $@ && make   @@ $@ is name of target, if my memory serves me right.
