Does this mean the libstdc++ is not mean to compile in environments that do 
not support C++ exceptions ? 

Please also think of embedded environment where size still matters. Not 
being able to compile a simple C++ program because even essential header 
files include bits/localefwd.h is a severe limitation in the use of this 
library. 

In my opinion a standard library should not impose any unnecessary burdons 
on its users. Requiring exceptions-support basically means that everybody 
who must not use exceptions has to rewrite and reimplement every bit of the 
standard library they need. 

I agree that __STL_THROW et al makes the code much more difficult to read. 
If there would be a better support for "no exceptions" then there could be a 
better solution (i.e. be able tell the compiler to ignore throw/catch 
statements). 


Thanks for considering,


Dirk.
