From the Makefile format, I think this should not be leading whitespace, but only leading tabs. Leading spaces in rules are a syntax error. Can you check whether \t instead of \s also works?

Good catch, Arne. Will check.

Looks like the 10th duplicate of Bug#17400.

Also good catch, Mauro. Can someone merge these 2 bugs?

But honestly: A more than 10 year old bug!!! About time we get it fixed!

I'll report back as soon as I have a new patch!
