 Subject: [Vala] error: Failed to execute child process (Exec format error)
   
My compiled valac says "error: Failed to execute child process (Exec
format error)"
any hints to trace what is the problem?

1. I have a pre-installed Mingw + msys on my win7 64 bits to compile
32bits applications.

Once you have made your executable formats consistent, be awarethe test suite will not run cleanly on Windows 
because of D-Bus.See https://bugzilla.gnome.org/show_bug.cgi?id=761307 for howsomeone resolved this on MSYS2.
