Problems with GCC 4.3 C++

["Horst H. von Brand" <vonbrand inf utfsm cl>]

A game (Linley's Dungeon Crawl's Stone Soup development line
<http://crawl-ref.sourceforge.net>, if you must know) did compile and work
with the GCC 4.1 series, but now it won't build. The construction it
complains about (after fixing what
<http://gcc.gnu.org/gcc-4.3/porting_to.html> suggests) is something like:

template <typename T>
static void ff(int i, T f)
{
  f(i);
}

void realf(int i, int j = 1000)
{
}

void g()
{
  ff(117, realf);
}

void gg()
{
  realf(37);
}

Note that the f() function can be called with one argument, and that is
what the template use tries to do; g++ complains:

  $ g++ -O2 -c tst.cc 
  tst.cc: In function ‘void ff(int, T) [with T = void (*)(int, int)]’:
  tst.cc:13:   instantiated from here
  tst.cc:4: error: too few arguments to function

I'm no C++ expert at all, so both the "how it used to work" and the current
behavior sound reasonable. Can somebody shed some light? Should this be
documented as a GCC change, or is it a bug?

gcc-c++-4.3.0-0.7.i386

Thanks!
