I suppose this all depends on the nature of the code. If you can get yourself into a situation where the Dwarf unwinder encounters a frame in the sjlj library when processing a throw, then it's got no choice but to terminate with an abort. > Like cygwin1.dll? > > Or, because cygwin1.dll exposes a very C-ish (not C++-ish) interface, > then what about other C++ libraries, such as xerces or ncurses++? I don't think this matters so much for Cygwin as it's built entirely with -fno-exceptions -fno-rtti and so it's EH-agnostic. But for existing C++ libraries I think the EH flavor may be a moot point because of another issue: if we go with shared libstdc++ (and to me everything indicates that we will need this for both performance and correctness) then those libraries will have to be rebuilt anyway even if EH doesn't change. Consider what happens if you have an existing C++ library built as a DLL with current g++ 3.4. Since the only option right now is static libstdc++, that means any libstdc++ code that the library needs is statically included in the DLL. Now consider that we get a g++ 4.3 that has a shared libstdc++, and you use that to create an .exe that links to that existing C++ library. Now you have (old library + its statically linked libstdc++ 3.4) linked to (new app + shared libstdc++ 4.x) which results in two different simultaneous versions of libstdc++ being present at runtime which sounds like a recipe for true horror if e.g. the main module and the library need to pass around std::string datastructures or whatnot. Once we pull the trigger on shared target libs I think there will be a period of instability during which we have to work out all these nightmares of libgcc and libstdc++ incompatibilities, but it's really something that we just have to grin and bear. Also this isn't exactly a new condition per se: remember that g++ changed ABIs between 3.3 and 3.4, so any C++ libraries would have had to have been rebuilt when we made that transition as well. I don't remember a whole lot of fuss back then (but maybe I just wasn't paying very close attention) which leads me to think that the number of actual C++ libraries in the distro may be small. Or maybe we just have a lot more packages today than we did then so it's an invalid comparison. Brian

Ultimately I guess I'd like to figure out a way to make unwinding and exceptions interwork with the native SEH to address the potential downside. (1) There was supposed to be a Google Summer of Code project addressing SEH in gcc.

[ITA] enscript: A free replacement for the Adobe's enscript program
Hi
I would like to adopt and maintain the enscript package from Gerrit P Haase.
o http://www.codento.com/people/mtr/genscript/ (Homepage)
o http://www.iki.fi/mtr/genscript/enscript-1.6.4.tar.gz (Download location)
Changes:
o Maintainer change
o Rebuild with latest build chain
o Switched to cygport build framework
o Doumentation, manual and info pages now under /usr/share/{man/info/doc}
hierarchy
Here is the setup.hint file:
sdesc: "A free replacement for the Adobe's enscript program"
ldesc: "GNU enscript is a free replacement for the Adobe's enscript program.
Enscript converts ASCII files to PostScript and spools generated PostScript
output
to the specified printer or leaves it to file. Enscript can be easily extended
to
handle different output media and it has many options that can be used to
customize
printouts."
