Compilation error on namespaces in system header debug.h
Hi,

I'm porting code from Windows to HP-UX 11, compiling with g++.
I'm getting a compilation error on the system's debug.h include file, which is included very indirectly through a series of other system include files. The one I am including is <map> .
The errors I am getting are:
/opt/hp-gcc-4.2.1/lib/gcc/ia64-hp-hpux11.23/4.2.1/../../../../include/c++/4.2.1/debug/debug.h: At global scope:

Following is the beginning of debug.h with the leading comment removed. The lines that get the errors are the declarations of nested namespaces, e.g. namespace __debug { }

Code:
#ifndef _GLIBCXX_DEBUG_MACRO_SWITCH_H
#define _GLIBCXX_DEBUG_MACRO_SWITCH_H 1

/** Macros and namespaces used by the implementation outside of debug
 *  wrappers to verify certain properties. The __glibcxx_requires_xxx
 *  macros are merely wrappers around the __glibcxx_check_xxx wrappers
 *  when we are compiling with debug mode, but disappear when we are
 *  in release mode so that there is no checking performed in, e.g.,
 *  the standard library algorithms.
*/

// Debug mode namespaces.
namespace std
{
  namespace __debug { }
}

namespace __gnu_cxx
{
  namespace __debug { };
}

namespace __gnu_debug
{
  using namespace std::__debug;
  using namespace __gnu_cxx::__debug;
}

How do I get this to compile?

Thank you!

GLPOPDEBUGGROUP(3G)						   OpenGL Manual					       GLPOPDEBUGGROUP(3G)

NAME

       glPopDebugGroup - pop the active debug group

C SPECIFICATION

       void glPopDebugGroup(void);

DESCRIPTION

       glPopDebugGroup pops the active debug group. After popping a debug group, the GL will also generate a debug output message describing its
       cause based on the message string, the source source, and an ID id submitted to the corresponding glPushDebugGroup() command.
       GL_DEBUG_TYPE_PUSH_GROUP and GL_DEBUG_TYPE_POP_GROUP share a single namespace for message id.  severity has the value
       GL_DEBUG_SEVERITY_NOTIFICATION. The type has the value GL_DEBUG_TYPE_POP_GROUP. Popping a debug group restores the debug output volume
       control of the parent debug group.

ERRORS

       GL_STACK_UNDERFLOW is generated if an attempt is made to pop the default debug group from the stack.

ASSOCIATED GETS

       glGet() with argument GL_MAX_DEBUG_MESSAGE_LENGTH.

SEE ALSO

       glPushDebugGroup(), glObjectLabel(), glObjectPtrLabel().
