Error: function std.stdio.setmode is not accessible from module a

[Kirill Kryukov via Digitalmars-d-learn]

Hello,

dmd 2.072.0 broke my project. I reduced it to following:
===== a.d start =====
import std.stdio;

void main()
{
    setmode(stdin.fileno, 0x8000);
}
===== a.d end =====

Compiling on Windows 7 64-bit with the following commands:

C:\utl\dev\D\dmd-2.071.2\windows\bin\dmd.exe a.d -ofa1.exe
C:\utl\dev\D\dmd-2.072.0\windows\bin\dmd.exe a.d -ofa2.exe

The first one succeeds (producing a working executable), the 
second one fails with these messages:

a.d(6): Deprecation: std.stdio.setmode is not visible from module 
a
a.d(6): Error: function std.stdio.setmode is not accessible from 
module a

2.072.0 changelog does not seem to mention anything relevant. Is 
there something obvious I'm missing, or should I file a bug 
report?

Thanks,
Kirill
