Hello,

    When I update the gcc, glibc, it comes to the compile error as bellow:

make[1]: Entering directory `/home/yangdy/workspace/click/userlevel'
  CXX ../lib/string.cc
In file included from ../lib/string.cc:22:0:
../include/click/string.hh:650:30: error: expected primary-expression before
‘,’ token
../include/click/string.hh:650:32: error: ‘real_data’ was not declared in
this scope
../include/click/string.hh:650:41: error: a function call cannot appear in a

   I don't know what case the problem?
   Thanks for your help!
