[pptp-server] PoPToP - MSCHAPv2/MPPE compile fails

[Jamin Collins]

I apologize for this post ahead of time, as I'm sure this has been asked and
answered several times before or I'm doing something wrong.  However, I've
skimmed the archives (couldn't find a search interface) and didn't find
anything that appeared to be related.

I've got PoPToP installed and configured on my Linux gateway.  I can connect
to it without a problem, but I also have absolutely no encryption working on
it right now.  I'm attempting to install the MSCHAPv2/MPPE patches as
outlined in the RedHat-PoPToP HOWTO.  I'm using the 2.2.16 kernel sources
from RedHat's RPMs, with ppp-2.3.10, and SSLeay-0.9.0b.  Everything is fine
right up until I try to compile the modules.  When I do, I get the following
list of errors:

Any ideas?
