Re: make distclean

[Juergen Sauermann]

Hi Mike,

I am not using the subdir-objects option. Should I ?

Also, if I

    ./configure
    make distcleran

then the compiler will not yet have been run.
But your explanation have given me an idea: if I remove the .deps directory
manually then 'make distclean' seems to work again.

Not very nice but at least  work-around.

Thanks,
Jürgen
