Umm, the stupid HP make which eats blank lines after a backslash also
does it to a backslash at the end of a comment line.

For example the following makefile,

-------------------------
# comment \

FOO=hello

foo:
        echo $(FOO) world
-------------------------

with gnu make will print "hello world", but with hp make prints only
"world".

Backslashes at the end of comments are a bit of a trap really, since
they eat the following line (both gnu and hp make), eg.

-------------------------
# comment \
more comment
-------------------------

As a suggestion, maybe automake could warn about this, perhaps
insisting you write

# comment \
# more comment

to keep it clear.
