$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/opt/bin:/c/Windows/System32:/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0/:/mingw64/bin

to delete all possible things in old Msys, I run
$ export PATH=/usr/local/bin:/usr/bin:/bin:/opt/bin:/mingw64/bin

$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/opt/bin:/mingw64/bin

$ vala ./hello.vala
Compilation failed: 3 error(s), 0 warning(s)
error: Failed to execute child process (No such file or directory)
error: Failed to execute child process (No such file or directory)
error: Failed to execute child process (No such file or directory)
