devel/flex updated to 2.6.1
---------------------------
* version 2.6.1 released 2016-03-01

** flex resources

*** The flex project is now hosted at github. Consider this a "period of
    transition". In particular, you should start at
    https://github.com/westes/flex for the flex codebase, issue tracking
    and pull requests.

*** New releases of flex are to be found at
    https://github.com/westes/flex/releases.

** flex internals

*** Flex now uses more modern and more standard names for variable
    types. There's more work to be done on that front yet, though.

*** A number of compiler warnings have been remedied.

*** Line directives should now work as expected and be absent when that is
    expected.

** test suite

*** When running the test suite, c++ files are compiled with the c++ header
    inside the flex distribution, rather than relying on the build system's
    flex header , which might not be installed yet or which might be out of
    date with respect to what flex tests expect.

*** Some portability fixes in the test suite such as opening files for
    reading in binary mode

** Building flex

*** The file src/scan.c asdistributed with flex source is now built with
    the current version of flex. Occasionally this had to be done manually
    to pick up new flex features. It's now just a part of flex's build
    system.

*** The pdf version of the manual is no longer distributed with flex,
    although if you have the texinfo package installed, you can still build
    it.

*** lots of general build system cleanup

*** the build system tries a bit harder to find libtoolize and texi2dvi.

*** When help2man and texi2dvi are missing, the error messages are now much
    more helpful.

** bug fixes

*** resolved github issues #53, #54, #55, #61.

*** Resolved sf bugs #128, #129, #155, #160, #184, #187, #195.
