First of all, please do not use "empty" lines inside a Makefile, it is
not an imperative language and care must be taken so that the parser
gets things right.
Doing a minimal test, I cannot confirm your findings, perhaps you should
try to trim down your example and see where it breaks or starts to work.
Example:
FILES=/etc/rc.conf /etc/doener.conf
all:
.for f in ${FILES}
.if !exists(${f})
@echo "${f} does not exist"
.else
@echo "${f} does exist"
.endif
.endfor
% make all
/etc/rc.conf does exist
/etc/doener.conf does not exist
hth,
