Hi Rainer,
I figured it out. Because you are using printf, you no longer need the '\\c'.
If I use the following RUN line, the test passes on both Windows/linux (I don't
have solaris to test unfortunately):
// RUN: printf '%%s\n' '/I%S\Inputs\cl-response-file\ /DFOO=2' > %t.rsp
I can submit this patch for you if you would like.

sorry about that. Unfortunately, I know next to nothing about Windows and
don't have access to any system to test.
That said...

... I should have looked at the autoconf manual first which has a whole section
on the can of worms that is echo and how to properly use printf instead.

The path not only contains \t, but \c as well, so the path is truncated after "
ools".

Judging from both the autoconf manual and my local testing, the following
should work properly:
// RUN: printf '%s\n' '/I%S\Inputs\\cl-response-file\ /DFOO=2' > %t.rsp
i.e. use printf '%s\n' to do the printing. I should have done this in the
first place since otherwise the response file wasn't newline-terminated.
Obviously that didn't matter on Solaris and Linux.
Once you've confirmed this works on Windows, I'll submit a proper follow-up
patch.
