You have in scope two definitions of ulong.  Remove the "using
namespace N;" line and all will be OK: nu will use the N::ulong
definition, and u the sys/types.h definition.

MLO@mlinux 33 $ cat foo.cxx
#include <sys/types.h>
namespace N {
  typedef unsigned long ulong;
}
int main()
{
  N::ulong nu;
  ulong u;
}
MLO@mlinux 34 $ g++ -std=c++98 -pedantic -W -Wall -o foo foo.cxx
foo.cxx: In function `int main()':
foo.cxx:7: warning: unused variable 'nu'
foo.cxx:8: warning: unused variable 'u'
MLO@mlinux 35 $
