Martin Sebor commented on STDCXX-673:
-------------------------------------

Okay, this sounds like a good plan for now. I checked your patch in as follows:
http://svn.apache.org/viewvc?rev=604073&view=rev

We will need to revisit this issue at some point before finalizing this though to make sure our typedefs are the same as those provided by the C library on every system. That will require us to either autodetect the underlying type of int8_t or hardcode it for the known platforms (conditionally, depending on the compiler macro defined in response to the option that control the signedness of plain chars). We'll likely end up with a combination of the two approaches.
