[92c9489] | 39 | <para>There were several static libraries that were not suppressed earlier

[73b2841] | 40 | in the chapter in order to satisfy the regression tests in several packages. These

[5b7d4da] | 41 | libraries are from binutils, bzip2, e2fsprogs, flex, libtool, and zlib. If desired,

[5cc2395] | 52 | <para>There are also several files installed in the /usr/lib and /usr/libexec

[c2863e6] | 54 | files. As already said, they are only useful when linking with static

| 55 | libraries. They are unneeded, and potentially harmful, when using dynamic

| 56 | shared libraries, specially when using also non-autotools build systems.
