Use flex 2.5.37, as the flex 2.6.* C++ lexer is broken (discussed on the Bison
lists): a stream pointer has been changed in the declaration to a reference
without doing it in the code. Reported some years ago on the flex list.

`configure` should warn or bail on incompatible flex versions. I suggest we add 
a version check in to ensure that flex version is between 2.5.37 
and 2.5.39 (given that 2.5.38 and 2.5.39 actually works).
