So I re-discovered the "and" operation

   CLIENT_AND_SERVER := $(and $(findstring true, $(JVM_VARIANT_SERVER)), 
$(findstring true, $(JVM_VARIANT_CLIENT)))
   ifeq ($(CLIENT_AND_SERVER), true)
     # Use the committed jvm.cfg for this 32 bit setup but add
     # minimal if needed
     $(JVMCFG): $(JVMCFG_SRC)
         $(call install-file)
         ifeq ($(JVM_VARIANT_MINIMAL1), true)
           $(PRINTF) "-minimal KNOWN\n">>$(@)
         endif
   else
     $(JVMCFG):
         @$(ECHO) C=$(JVM_VARIANT_CLIENT) S=$(JVM_VARIANT_SERVER) 
BOTH=$(CLIENT_AND_SERVER)

Yet I always execute the else but print:

C=true S=true BOTH=true


I'm stumped! :(

Thanks,
