source: trunk/configure.ac @ 171

Last change on this file since 171 was 171, checked in by Jari Häkkinen, 15 years ago

Fixes #72. Introduced libtool to create a static svndigest. Libtool
creates partially static libraries, i.e., links all functions from
static libraries available and performs shared linkage to the rest.

  • Property svn:eol-style set to native
  • Property svn:keywords set to Id
