Bugzilla Bug 122365

Fails to compile.  I believe this problem is from flex, according to what I am
reading from a old bug on debian.  Most likly the patch for flex broke this,
though I am not fully certain to be sure.

These are the packages that I would merge, in order:

tetex-2.0.2-r5 also broken from same thing.  Both of these packages has been
marked stable on most systems.

I don't have time to look at it this weekend.
It seems that the following bug from debian is about the same issue:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=191942

Are you sure you don't try to mix a stable and unstable gentoo system (since
you helped with the tetex-3 problems)?
If you are could you please try to locate which version of flex that breaks
tetex.

I do admit that this can be caused by an issue of mixing unstable with stable;
which when ever my system finishes updating my system.  I will go through the
process of finding out which version of flex breaks tetex.  If anything it may
help prevent this problem for someone else that uses flex more heavily then I
do (which would be a decent reason for using unstable flex on stable system).

*** Bug 122568 has been marked as a duplicate of this bug. ***

flex 2.5.31 causes the breakage.  It works fine with flex 2.5.4a

Fixed in CVS by using the supplied lexer (lex.yy.c-dist).
Thanks Chris for reporting and the pointer to the similar debian bug.
