Issue ID: 13034 Summary: [GIT HEAD] core.stdc.stdio - deprecation warning with dmd -inline Product: D Version: D2 Hardware: All OS: Windows Status: NEW Severity: regression Priority: P1 Component: DMD Assignee: nob...@puremagic.com Reporter: ga...@mail.ru I just compiled the latest git HEAD version of druntime+phobos on Windows. After that, when I import std.stdio in any D program and compile using DMD with "-inline" option, it gives me deprecation warnings in core.stdc.stdio. In fact, I see the same warnings even when compiling druntime itself. I followed these instructions to build DMD&friends from source: http://wiki.dlang.org/Building_DMD#Windows_2 . Every other aspect of the compiler is working fine for me so far. I'll note that it's the first time I built it from source though.
