Can me somebody explain that? o.O

isSomeString!T regression? See enum & std.traits topic in d.D.
Seems like it will work again in 2.061...

Yeah. In 2.060, std.traits doesn't treat enums as their base type for stuff like isSomeString and isIntegral, which is the problem. It's been fixed on github, but it's still broken in 2.060.

Which file must i replace with his version from github to solve the problem?

I really wouldn't advise grabbing single files like that. The release was recent enough that it may be okay, but in general, that's just asking for trouble - especially with something as integral as std.traits. But if you really want to, this is the relevant pull request:

https://github.com/D-Programming-Language/phobos/pull/739

std.conv, std.format, std.stdio, and std.traits were all changed as part of the fix.

Fails on Win7 with:
Error: don't know how to make '..\druntime\lib\druntime.lib'

Quick question: I've asked that for some time: why is it std.stdio and not std.io?

I don't remember. Probably because it's stdio.h in C/C++.

But Steven Schveighoffer is working on a replacement for it which will probably be named std.io. So, in the long run, that's probably what we'll end up with.

And why ends my compilation with this error?
To cast any Token is _very_ annoying. -.-

You're going to need to build both druntime and Phobos if you want to build Phobos. I don't know what's in the zip file, since I haven't used it in ages, so I don't know if you can build them from what's in there or whether you need to actually grab them from github.

I have no idea what you're talking about.
