[PATCH] OS/2 supports

Hi/2. I attach the patches for OS/2 supports. Review, please.

[PATCH 01/10] Add -shortname option.

OS/2 limits a length of a DLL base name up to 8 characters. If a name of a shared library is longer than 8 characters, OS/2 cannot load it. So the option to specify a short name is needed. --- NEWS |1 + build-aux/ltmain.m4sh | 11 +++ doc/libtool.texi |4 ++
