[Vala] Vala on Windows

[gerhard gruber documatrix com]

Hi,

I have created an application using Vala and tried to compile it on Windows, but the application needs Vala 
> = 0.14.0 and Vala for Windows binary is just available in the version 0.12.0 - so I tried to compile it on 
my own using MinGW and mingw.sh (http://code.google.com/p/vala-win32/source/browse/trunk/mingw.sh?r=5) :)

But after some hours I got stucked with the error, that sys/wait.h could not be found:
scanner.c:34:36: schwerwiegender Fehler: sys/wait.h: No such file or directory

I think, that this header-file is not available on windows, is it?

So is it still possible to compile Vala on Windows and if it is so, how?

Thank you for your help.
