configure: quit on trying to get ICC and Flex be friends

Browse Source 
The CI is using Flex 2.5.35.  And ICC is too picky for it.  Let's stop
making these warnings errors.  I wish I could disable them in the
source files using the ICC version and the Flex version, but ICC's
pragma support is unclear, and I'm tired of fighting it.

* configure.ac (FLEX_SCANNER_CXXFLAGS): Make warnings warnings.
* examples/c++/local.mk: Comment changes.
