Hmmm. I'm using hand-coded makefiles, by my dependency files only have
relative paths in them. I generate them using this option on the gcc
command line:

-MMD -MF $(@:.o=.d)

Yeah - it's getting confused by te extra colons in the 'C:/directory'

Cygwin is trying to be like linux and not like windows. So it tends to
following the linux defaults so that tools and stuff from linux
compile/build more seamlessly.

Only if you use absolute paths. My stuff works equally well on both
environments, because it's using relative paths.
