egcs 1.1.1 : 2 missing features

[Pasha Murat]

Dear EGCS developers,
	first of all - my congratulations with the new release! It is a real
step forward. Let me however report on 2 features of ANSI C++ which still 
seem to be not supported in egcs 1.1.1 (I apologize in advance if I'm 
missing smth). 

- I failed to find `bitset' (or `bitset.h') include file corresponding to 
  STL `bitset' class
- it seems that support of namespaces is still sort of limited - the piece
  of code enclosed below doesn't compile.

		You guys are doing a great job! -thanks, pasha.
