Oops, there's a make distcheck...? Now it works.
Revision 1.4 2004/11/25 18:27:03 marc
additional test for release and reset
Revision 1.3 2004/08/28 16:21:25 marc
mrw-c++-0.92 (mrw)
- new file: version.cxx
- new file header for all sources
- work around warning in mrw::auto<T>
- possibility to compile without log4cxx
- work around bugs in demangle.h and libiberty.h
- corrections in documentation
- added simple tracing mechanism
- more warnings
- small corrections in Auto<>::Free and a new test for it
- possibility to compile without stack trace
