By the way, does it help if you use a newer glibmm (such as 2.10). I don'=
t
think that glib 2.10 and glibmm 2.10 will bring in extra dependencies.

Oh ignore that. That's no good for gtkmm 2.2.

Simply put, the TreeViewColumn has a construct of the form
class A {
public:
  ...
  template<class T> A(T arg);
};

template<class T> inline A::A(T arg)
{
  <Do the object init>
}

The patch changes that to

class A {
public:
  ...
  template<class T> A(T arg)
  { <Do the object init> };
};

These are two fully equivalent ways of defining an inline method (templat=
e),
and I don't think you can generally say that one is "better" or "more cor=
rect"
than the other. However, g++ versions prior to 4.1 apparently have a bug =
in the
handling of constructors that are function templates, that under certain
conditions causes a compiler crash during template instantiation (i.e. wh=
en
compiling code that uses the constructor in question.) I'm not sure what
excatly those conditions are, but I found that the crash stopped occuring=
 for
the gtkmm example code, and also some of my own tests, after I changed th=
e code
layout as indicated above.

This may be relevant in conjunction with another incarnation of this issu=
e,
however:

I find that the fix doesn't really work when building gtkmm 2.6.5 on top =
of
glibmm 2.6.1 using "MinGW" gcc. The addition of GTKMM_API makes no differ=
ence,
as the macro will in fact have an emtpy body. "__declspec(dllimport)" is
included if, and only if, GLIBMM_DLL is defined, which it actually isn't.=
 This
should be clear from the following section of glibmmconfig.h:

#if defined(_WIN32)
// Win32 compilers have a lot of varation
#if defined(_MSC_VER)
#define GLIBMM_MSC
#define GLIBMM_WIN32
#define GLIBMM_DLL
#elif defined(__CYGWIN__)
#define GLIBMM_CONFIGURE
#elif defined(__MINGW32__)
#define GLIBMM_WIN32
#define GLIBMM_CONFIGURE
#else

So perhaps this bug ought to be reopened (can't do it myself...), or shou=
ld I
add a new one?
