The second of the tests using the new dg-set-compiler-env-var directive is
doing
/* { dg-set-compiler-env-var SOURCE_DATE_EPOCH "AAA" } */
and then expecting an error. If the env var isn't restored, then on any of
the following testcases that uses __DATE__ and similar macros the env var
contains still AAA and thus results in an error.
