| 11 | best left alone, so we recommend you unsetting CFLAGS, CXXFLAGS and other

[2b1174be] | 48 | <para>The missing msgfmt (from the gettext package which we will install

| 50 | already pre-built, so you won't be missing out on anything. You would
|
---|
| 51 | only need it if you make changes to the Glibc manual files. Since we
|
---|
| 52 | don't do this by default, we can safely ignore it.</para>
