_NEWLIB_VERSION exposure through sys/cdefs.h
Wed Sep 17 21:09:00 GMT 2014
In libc++, we'd like to be able to tell when the underlying libc is Newlib. At
the moment, that requires us to do things like this:
#if defined(__has_include) && __has_include(<newlib.h>)
The problem with that strategy is that it does not work when using gcc, as it
doesn't have __has_include support yet. It came up in discussion that
sys/cdefs.h might be the right place for that, as that's where glibc puts __GLIBC__.
Would there be an objection to #include <newlib.h> from sys/cdefs.h? Is there a
better way to detect Newlib that I've overlooked?
