Revision 1.9 2005/04/19 18:48:00 marc
new feature PartialExec
Revision 1.8 2005/04/07 20:55:21 marc
Oops, there's a make distcheck...? Now it works.
Revision 1.7 2004/12/20 13:21:21 marc
exception tests: each exception must be in an own test case
Revision 1.6 2004/12/14 20:30:10 marc
added possibility to pass string to stdin of child process
Revision 1.5 2004/10/13 10:43:11 marc
test for bad exception specification
Revision 1.4 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
