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