Re: whitespace

[ali hagigat]

Dear Paul Smith,
Thank you very much for your valuable comments.
Please look at the following example, its output and the extract of
the documentation:
----------------------------------------
var1='rrrr\
        ffff'
var2='rrrr     ffff'
all:
        @echo $(var1)
        @echo $(var2)
        @echo 'rrrr\
           ffff'

The output:
rrrr ffff
rrrr     ffff
rrrr\
           ffff

----------------------------------------
5.1.1 Splitting Recipe Lines
In this situation the newline quoting rules for makefiles will be
used, and the backslash-newline will be removed.
----------------------------------------
make not only removes backslash-newline for echo $(var1)
but also white spaces!
Regards
