It's not surprising it fails in most compilers, since std::map needs
at least two template arguments.  But I can't get GCC to accept fewer
than two either.  Can you post a complete minimal example of a program
that demonstrates this?

That's strange.  Why is "instantiated from here" an error?
I tried compiling your example and I get this:

test.cpp: In method `M<int>::M(const int &)':
test.cpp:12:   instantiated from here
test.cpp:6: warning: statement with no effect

There are no errors and I get a working executable.  Your compiler
messages also have a different format than mine.  What version
of gcc are you using (gpp --version)?
