[C++-sig] Improvements on Mac OS X

[Harri Hakula]

Good news: With the very latest gcc from Apple everything compiles 
without errors.

Bad news: The problems in running the examples persist.

For one fleeting moment I had everything in the example-directory up 
and running...
Then I changed something :-( and broke my setup!

However, I am confident that somewhat more knowledgeable can figure out 
the right flags
for linking actions. (Yes, I was playing -undefined suppress 
-flat_namespace games when my house of cards fell apart.)

Cheers,

	Harri
