43 | <para>This package and the next two (Expect and DejaGNU) are installed
|
---|
44 | to support running the test suites for GCC and Binutils. Installing
|
---|
45 | three packages for testing purposes may seem excessive, but it is very
|
---|
46 | reassuring, if not essential, to know that the most important tools are
|
---|
47 | working properly. Even if the test suites are not run in this chapter
|
---|
48 | (they are not mandatory), these packages are required to run the test
|
---|
49 | suites in <xref linkend="chapter-building-system"/>.</para>

64 | <para>The Tcl test suite is known to experience failures under certain host

65 | conditions that are not fully understood. Therefore, test suite failures

66 | here are not surprising, and are not considered critical. The

68 | Universal Time (UTC), also known as Greenwich Mean Time (GMT), but only
