Re: [Opalvoip-devel] More background on changing BOOL to bool

[Derek S. <de...@in...>]

Hi,
 I am happy with this change.

It is a good move to adjust our code to better coincide with the C++ 
standard. If the compiler can spot more bugs, great.

If the compiler can give smaller faster code, great.

If it costs a bit of pain for us, sigh. 
 
As for the backwards compatibility, well, it is nice to have. But if it 
can't be achieved, remember the saying, "there is no gain without pain"

Derek.
