The ':tW' variable modifier seems to be pmake/fmake syntax.
At least it doesn't work using my Make (9201120530, FreeBSD 9.1 RELEASE)
Is there any similar, non-documented, "treat-as-one-word"-modifier
avilable for FreeBSD Make?

Yes, finally we end up with a .PHONY target, which isn't useful in a
real-case Makefile.
Any targets containing whitespaces will always be rebuilt even if
they're up to date.
I guess my final solution will be :
"Warning:
You are using FreeBSD Make, and one or more of your directories/files
contains whitespaces.
Either rename your targets (recommended), or stick to GNU Make."
Thanks for the input, regards,
Johan
