Merged revisions 97889 via svnmerge from

https://origsvn.digium.com/svn/asterisk/branches/1.4 ........ r97889 | murf | 2008-01-10 14:37:10 -0700 (Thu, 10 Jan 2008) | 1 line Applied the same fixes for ael.flex as was done in 97849 for ast_expr2.fl; overrode the normally generate yyfree func with our own version that checks the pointer for non-null before passing to free(). Also takes care of a little problem with 2.5.33 and the use of the __STDC_VERSION__ macro. ........ git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@97890 65c4cc65-6c06-0410-ace0-fbb531ad65f3
