So, I moved the fix into the flex input itself. Then, I found when I used flex 2.5.33, that it was using __STDC_VERSION__, and that's not real good; so I added back in a DIFFERENT sed script to fix that little mess. Tested everything, a couple different ways. Hope I did no harm, at the least. ........ git-svn-id: http://svn.digium.com/svn/asterisk/trunk@97850 f38db490-d61c-443f-a65b-d21fe96a405b
