When I originally learned C++ about 10 years ago, I thought
I heard clearly that C++ structs do not allow member functions and
that they do not allow inheritance. Recently I noticed
that g++ allows these. I haven't been following C++'s
development closely so I am just curious, when did C++
begin to allow these, or rather, did I misunderstand the
situation at the start? Also, what are the current differences
between struct and class?

You must have been taught incorrectly:

From C++98 on there was no difference between the keywords struct and

class used as a /class-key/, except that 'struct' causes the default
member and base class access to be public instead of private when
'class' is used. Even, if you actually meant C++ POD types, it was
always to possible to have those with non-virtual member functions. Only
recently C++0x extended these POD types even more: It is now OK to have
private data members or a base class, for example.
