The TestScript/list_ambiguous_path test in cmd/go fails when the Windows language is set to something different from English, because the test hardcodes the missing file error message, which is localized.
An example failure from a system with the language set to Italian:
--- FAIL: TestScript (0.01s)
--- FAIL: TestScript/list_ambiguous_path (0.36s)
# Ensures that we can correctly list package patterns ending in '.go'.
# See golang.org/issue/34653.
# A single pattern for a package ending in '.go'. (0.060s)
# Multiple patterns for packages including one ending in '.go'. (0.057s)
# A single pattern for a Go file. (0.144s)
# A single typo-ed pattern for a Go file. This should
# treat the wrong pattern as if it were a package. (0.049s)
# Multiple patterns for Go files with a typo. This should
# treat the wrong pattern as if it were a non-existint file. (0.035s)

This test is run by all.bat, which means that all.bat will not complete successfully on a non-english Windows machine.
