These were added in C99 to avoid interferring with C++, but then C++11 caught up with inttypes/h/stdint.h and removed the need for the macros. They have disappeared from C11 as a result, and also from current glibc implementation (https://sourceware.org/bugzilla/show_bug.cgi?id=15366) So it seems reasonably safe to do the same, and it will save people having to enable access to these macros explicitly when writing C++.
