Re: raising minimum version of Flex
I'm not at all impressed with the recent series of flex releases, since it
started using m4 internally and passing user code through m4.
(cf. bison, which unlike
flex pays proper attention to assuring that arbitrary valid parsers are
not mangled by m4).
Fully agreed. The recent releases of flex are a mess (a pity, because
they also have interesting features such as yylineno support without
performance hits).
