GNU libtoolは汎ライブラリ開発者向けのスクリプトです。一貫性のある移植可能なインターフェースにより、さまざまなプラットフォームで共有ライブラリと静的ライブラリを使う複雑さを回避します。libtoolはすべてのプラットフォーム上で、静的ライブラリの構築をサポートします。（一部のプラットフォーム上では共有ライブラリの構築をサポートしません。） http://www.gnu.org/software/libtool/libtool.html
Lots of minor bugfixes were made involving libtool's behavior in AIX, OpenBSD, IRIX, and others. The program was also updated to support more recent versions of its dependencies.
Loading failure error messages from libltdl were improved and memory leaks in libtdl were plugged. Support for OpenBSD was improved. Here-doc files are no longer left behind. Libtool now builds with autoconf-2.50 and higher. Better performance on HP-UX is now obtained by using shl_load as opposed to using dlopen.
This release bootstraps with autoconf-2.50 and automake-1.4-p4. An attempt is
always made to build at least a static library, even if both static and shared
libs were disabled. Full support for C++ compilers and the GNU gcj compiler was
added. libltdl can now load all modules in a given path according to
user-supplied criteria with the `lt_dlforeachfile' call. Support for AIX ia64,
djgpp, HPUX, HURD, OpenBSD, and SCO3.2* was improved. Internal mutex handling
no longer has namespace clashes on NCR MP-RAS. New pdemo and tagdemo tests were
added. Other bugfixes were made.
