[52d29f7] | 21 | <para>There are two reasons for installing
|
---|
| 22 | <acronym>GCC</acronym>-&gcc2-version;. The first is that the kernel
|
---|
| 23 | developers have certified <acronym>GCC</acronym>-&gcc2-version; as the
|
---|
| 24 | preferred compiler for compiling the kernel. The other (and more compelling
|
---|
| 25 | reason) is that some commercial closed-source packages (such as Netscape
|
---|
| 26 | Navigator, Yahoo Pager) and precompiled packages (such as Mozilla)
|
---|
| 27 | are linked against <acronym>GCC</acronym>-&gcc2-version; libs.</para>
