[sigc] Problem compiling on debian unstable.

[Marco Scholten <mscholtn xs4all nl>]

I am trying to build gtkmm with jhbuild but i get stuck on building sigc
++.

platform: debian unstable
g++ (GCC) 4.0.3 20051111 (prerelease) (Debian 4.0.2-4)

I get a lot of errors but it all starts with:

g++ -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I.. -g -O2
-Wp,-MD,.deps/signal_base.pp -c signal_base.cc  -fPIC -DPIC
-o .libs/signal_base.o
../sigc++/trackable.h:76: error: typedef name may not be a
nested-name-specifier
../sigc++/trackable.h:76: error: expected ';' before '<' token
../sigc++/trackable.h:77: error: 'callback_list' does not name a type

Any hints?

Thanks,
Marco
