bug#6681: 23.2; "Save Error" from semantic

[Eric M. Ludlam]

Yes, I've seen this before.  Here is a thread:

http://permalink.gmane.org/gmane.emacs.cedet/3995

Kai had a hook that expected a buffer to always exist in his c mode 
hook.  Semantic's parser has to create c mode buffers with no file in 
order to build up text from macros to parse it.  The error gets caught 
in the wrong place, and bogus stuff gets into the macro table that only 
turns up later.

The latest semantic-c.el in CEDET/CVS, as the thread suggests,will ask 
if the user wants to debug their hooks if this happens.

semantc-lex-spp.el in CEDET/CVS has a little more error checking there too.

My latest papers for the next 6 months should have arrived at the FSF a 
while ago, so if you need to merge anything, it should be good.
