Re: Building 2.5.20

[Daniel Johnson]

I had the same problem.  From what I've read, the flex API has changed
since 2.5.4a.  Here's what I did to fix it:

sed -i -e 's:\$\(FLEX\) :\$\(FLEX\) -l :' stepmake/stepmake/c-rules.make

The "-l" flag tells flex to behave like old-school lex.  It seems like
the configure script should take care of this, though.
