To maintain source compat, we shouldn't undef the stuff we have. First, we should ensure that the c++-11 types are defined one way or another, and then typedef the old resip int types based on the standard types. Then, begin converting the resip codebase over to the standard ones entirely (easily scriptable, and not likely to result in funny stuff like "this std::vector of conditions" in a license block).
Best regards,

Using the new types will make it more natural for people new to the
codebase as well
I'm going to start doing this in trunk today and we simply need to have
a plan for compatibility before taking it into the release branch
I would propose that:
- with a C++11 build, we use <cstdint> (#if __cplusplus >= 201103L)
and define stuff like:
using std::uint8_t;
using std::uint32_t;
because we are not "using namespace std;" in every source file.
- we fall back to <stdint.h> if possible (#ifdef HAVE_STDINT_H from
autotools / config.h)
- if that fails, we define the C++11 types ourselves in
rutil/compat.hxx (#ifndef uint32_t) using typedef
Does this seem reasonable and likely to work widely? Have you seen
alternative approaches or extra things I should add?
