Re: caching included makefile contents

[Noel Yap]

After speaking to someone here, it was pointed out that the line "$$(__FILE__)" 
is completely wrong.  I've changed it to:

  $$(eval $$($$(__FILE__).contents))

which generates the error:

GNUmakefile:39: *** invalid syntax in conditional.  Stop.

which is the exact error I get if, rather than using the function, I use the 
line:

ifndef A.mk A.mk := 1  A: B     touch $@  .PHONY: clean-A clean: clean-A  
.PHONY: clean-A clean-A:     rm A  $(call include-makefile,B.mk)  endif

which is the contents of the included makefile without line breaks.

Any suggestions on how to work around this?

Thanks,
Noel
