EGCS 1.1b bug: template specialisation of static data members

[Lassi A. Tuura]

Hi,

EGCS 1.1b (on Linux RH5.1 at least) does not seem to differentiate
between declarations and definitions template specialisations of
class-static data members ([temp.expl.spec] 14.7.3/14 in Dec '96 draft). 

Example `bug.cxx':
----
struct X;
template <class T> struct Y { static const X array[]; };
template <> const X Y<int>::array [];
struct X {};
template <> const X Y<int>::array [] = { 0, 1, 2, 3 };

For some other code of mine I also get the following error before any of
the above (`interfaces' is the array):
  /afs/cern.ch/user/l/lat/public/work/src/Control/Net/Net/Module.h:27: 
  array size missing in `ComponentTraits<Module>::interfaces'

With sufficient thrust, pigs fly just fine.  However, this is not
necessarily a good idea.  It is hard to be sure where they are going
to land, and it could be dangerous sitting under them as they fly
overhead.  --RFC1925, "The Twelve Networking Truths"
