| 18 | <para>This package and the next two are only installed to be able to run the
|
|---|
| 19 | test suites for GCC and Binutils. Installing three packages just for testing
|
|---|
| 20 | purposes may seem like overkill, but it is very reassuring, if not essential,
|
|---|
| 21 | to know that our most important tools are working properly. Even if you are
|
|---|
| 22 | not running the test suites here in this chapter as per our recommendation,
|
|---|
| 23 | these packages are still required for the test suites in the next
|
|---|
| 24 | chapter.</para>

| 35 | <para>(If you insist on testing the results, then issue:

|
|---|
| 37 | to experience failures under certain host conditions that are not fully
|
|---|
| 38 | understood. Therefore, test suite failures here are not surprising, and are not
|
|---|
| 39 | considered critical. The <emphasis>TZ=UTC</emphasis> parameter sets the time
|
|---|
| 40 | zone to Coordinated Universal Time (UTC) also known as Greenwich Mean Time
|
|---|
| 41 | (GMT), but only for the duration of the test suite run. This ensures the clock
|

| 42 | tests are exercised correctly. More information on the TZ environment variable
