Hi there,

I am not sure I understand the question (and I am not familiar with Cygwin).
The answer to the question "Why is there C++ in my libppl" is that libppl
is written in C++.  The C interface to the PPL, libppl_c, is also written
in C++.  Your description of the problem confuses me, as it seems to be
system-independent;  however, I have no problems bootstrapping HEAD on my
GNU/Linux system.  What am I missing?
All the best,

    Roberto
