Description of problem:
trying âmake checkâ in oprofile source root Iâve got a message from my 
compiler:

There is a typo in sources I believe: bad_regex:: bad_regex is declared 
in global namespace in op_regex.h but defined in unnamed namespace 
in op_regex.cpp. Itâs definition should be moved out of the unnamed 
namespace (as regular_expression_replace members are defined 
outside of this namespace later in the file).
Here is the patch for this move:

 using namespace std;

-namespace {

        :
        op_exception(pattern)

+namespace {

 string op_regerror(int err, regex_t const & regexp)
 {

By using standart/accustomed language constructs oprofile would get 
more portability between platforms/compiler so please consider applying 
this patch despite there is no error emitted with current version of g++ 
(3.2.3).


Version-Release number of selected component (if applicable):


How reproducible:
always

Steps to Reproduce:
1. Get Intel compiler (better 8.0) anywhere
2. do 'rpm -bc' using any compiler
3. try 'make check' in source root using Intel compiler: make check 
CXX=icpc
  
Actual results:
Compile-time error

Expected results:
no compile-time errors
