thanks for your report.  The latest snapshot of egcs says:

t.cc:6: type/value mismatch at argument 1 in template parameter list for `template <class _Key, class _Compare = struct less<_Key>, class _Alloc = class allocator<_Tp1>> set<_Key,_Compare,_Alloc>'
t.cc:6:   expected a type, got `A'
t.cc:6: template argument 1 is invalid
t.cc:6: template argument 2 is invalid
t.cc:6: template argument 1 is invalid
t.cc:6: template argument 3 is invalid
t.cc:6: warning: ANSI C++ forbids declaration `x' with no type
