New Revision: 309033
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=309033
Log:
A later version of flex already includes the fwrite workaround code, which if used twice causes a compilation error.
Detect whether Flex will compile without the workaround; if so, suppress our workaround code.
