1# This test checks that the CC environment variable may contain quotes and
2# spaces. Arguments are normally split on spaces, tabs, newlines. If an
3# argument contains these characters, the entire argument may be quoted
4# with single or double quotes. This is the same as -gcflags and similar
5# options.
