Logging logs in Windows

[Alexander Zhirov]

I wrote a small utility in Linux. I want to build it for Windows. 
He swears at some parts of the code like this:

```powershell
C:\sources\pxe-restore>dub build -b release
     Starting Performing "release" build using dmd for x86_64.
     Building pxe-restore ~master: building configuration 
[application]
source\azh\log.d(3,8): Error: module `core.sys.posix.syslog` 
import `syslog` not found
source\azh\query.d(7,8): Error: module `core.sys.posix.syslog` 
import `LOG_NOTICE` not found
source\azh\query.d(7,8): Error: module `core.sys.posix.syslog` 
import `LOG_ERR` not found
source\azh\query.d(7,8): Error: module `core.sys.posix.syslog` 
import `LOG_INFO` not found
source\azh\query.d(7,8): Error: module `core.sys.posix.syslog` 
import `LOG_WARNING` not found
source\app.d(12,8): Error: module `core.sys.posix.syslog` import 
`LOG_NOTICE` not found
source\app.d(12,8): Error: module `core.sys.posix.syslog` import 
`LOG_ERR` not found
source\app.d(12,8): Error: module `core.sys.posix.syslog` import 
`LOG_INFO` not found
source\app.d(12,8): Error: module `core.sys.posix.syslog` import 
`LOG_WARNING` not found
Error dmd failed with exit code 1.
```

A small fragment of the code used:

```d
...
import core.sys.posix.syslog : LOG_NOTICE, LOG_ERR, LOG_INFO, 
LOG_WARNING;
import core.sys.posix.syslog : syslog;
...
void log(int priority, string message)
{
     syslog(priority, (message ~ "\0").ptr);
}
...
```
