Re: recursive functions in a Makefile

[Dylan Cuthbert]

great, sorry about the character set,  I must have let a japanese character
through somewhere as it normally defaults to the western europe iso
standard.

Glad to hear about the cvs change to enable call recursion.

Just a simple change but it'll really improve the functionality available
from within a Makefile.

Which version of Make will that appear in?

Regards
