[dmd-internals] AutoTester breaking

[kenji hara]

Now AutoTester result is breaking.
http://d.puremagic.com/test-results/

It seems to me there is some problems.

- Breaking of dmd/test/runnable/test23.d

> runnable/test23.d(692): Error: undefined identifier package c.stdlib
> runnable/test23.d(702): Error: undefined identifier package c.stdlib
> runnable/test23.d(724): Error: undefined identifier package c.stdlib
> runnable/test23.d(734): Error: undefined identifier package c.stdlib

I have posted pull request. That may fix Posix dmd tests excepting OSX.

- Breaking std.socket in OSX

> std/socket.d(355): Error: std.c.osx.socket.IPPROTO_RAW at std/c/osx/socket.d(39) conflicts with core.sys.posix.netinet.in_.IPPROTO_RAW at ../druntime/import/core/sys/posix/netinet/in_.di(413)

It seems that is symbol definition duplication.
Unfortunately, I don't have OSX.

- Breaking Phobos test in Windows

I think this is AutoTester environment problem.
Because the all builds and tests are succeeding in my PC (Windows 7 64 bit).
It is *false positive* IMO.

- Breaking std.regex in FreeBSD32

> core.exception.AssertError at std.regex(2900): Assertion failure

I don't know why.
