Package: flex
Version: 2.5.37
Maintainer: Manoj Srivastava <sriva...@debian.org>
Description:
Multiple <<EOF>>'s are not supported as per Section 12
End_Of_File Rules. Example 1 demonstrates that multiple
<<EOF>>'s are supported if each <<EOF>> is prefixed with
a start condition. Example 2 shows what happens if each
<<EOF>> is not prefixed with a start condition. Example 3
from Section 12 specifically allows Example 2.
Please address this as a code change and not a documentation
change.
