I will check carefully the mailing list in future.
currently, I am confused because the same code can be compiled in
C++Builder and Visual studio 2008, but not gcc.
I will carefully check the link you posted a little later.
Thanks!

Hello,
I have following code,
in gcc 4.8.4, the code can NOT compile, because of an error:
error: need ‘typename’ before ‘std::map<K, V>::iterator’ because
‘std::map<K, V>’ is a dependent scope
however, I can compile the same code in other C++ compiler(borland c++),
whether there are some differences between gcc template syntax?
Thank you very much!
As explained at https://gcc.gnu.org/lists.html the gcc@xxxxxxxxxxx
mailing list is for discussion of GCC development. If you want help
using GCC please use the gcc-help list instead. I have redirected your
question there.
GCC supports standard C++, which says your code is not valid, for the
reasons GCC gave you in the error messages.
See https://womble.decadent.org.uk/c++/template-faq.html#disambiguation
for an explanation.
