Here is what I have:
all :
@list=REFRESH+ldb+celltools+pub ;\
if ! [ -z "$($list)" ] ; then \
echo "list = '$$list'"; \
fi
I need to determine if the variable REFRESH+ldb+celltools+pub exists
in the make world. This name is normally generated for values passed
in to a define.
I believe that the -z will tell if a sh variable has no value, but that
refers to a sh variable.
I need for sh functions to determine if a make variable exists.
