Well that seems OK.
Now try 'valac hello.vala --ccode' and see if you get the error.The --ccode will by pass this block of 
code:https://git.gnome.org/browse/vala/tree/compiler/valacompiler.vala#n468
If you don't get the error then it means the error is in that block somwhere.There are a number of GLib 
functions that call out to the operating system. 
These could be causing your error:Environment.get_variable ()and from 
https://git.gnome.org/browse/vala/tree/codegen/valaccodecompiler.vala#n51Process.spawn_command_line_sync ()
You could try small test Vala programs to see which of those are causing the problem.As to the solution if 
Process.spawn_command_line_sync () is not working on MSYSI don't know. Make the leap to MSYS2 so you are 
following an active packaging system?
