I've this simple makefile:

VAR=one

all	:	main

main	:
	@echo ${.CURDIR}
.if ${.CURDIR}
	@echo ${VAR}
	VAR=two
	@echo ${VAR}
.endif

When I output VAR second time, the value is still "one", and not the
new value "two". Why?

% make
/usr/home/mexas
one
VAR=two
one

And gmake gives an error:

% gmake
makefile:7: *** missing separator.  Stop.
% 

please help
many thanks
anton
