[krbdev.mit.edu #6851] pkinit can't parse some valid cms messages

[Greg Hudson via RT]

The patch looks reasonable, but fails to build on Ubuntu Lucid, and 
probably on any system with an OpenSSL 0.9.8 version.  Although 0.9.8g 
claimed to include a backport of the CMS functionality, it doesn't appear 
to install cms.h, and neither does any version of 0.9.8 as far as I can 
tell.  (In fact, 0.9.8g doesn't appear to have CMS source files either; 
those showed up in 0.9.8h.)
