I see that one post there is missing from the archives, I wonder why? So
I copy'n'paste it here (actual answer is at the bottom):

> There are indeed some problems with fedora 4 and gcc 4. Gcc 4 generates error when it  encounters some anonymous  enum (it was not the case with previous version of gcc). It means it is no longer possible to write something like "enum {value = 1 }". You now have to write "enum enumname {value = 1 }". The problem is that under fedora 4 the default compiler is gcc4 and that some header files from stl still contain anonymous enum !!.  Basically what you have to do is to edit those .h files and put some stupid useless name to the enum.
> If I remember correctly I had  to modify the file /usr/include/c++/4.0.1/bits/cpp_type_traits.h (of course if you have only gcc 4.0.0 replace 4.0.1 with 4.0.0 :) ).
