I had a quick look, and I surmise that the LDC folk switched from Mercurial to Git but didn't communicate with the Debian packager that this was going to happen. Since the Mercurial repository hasn't changes in the last two years, neither has the Debian package. The ldc package got ejected from Testing so will not be in the next Debian release. Can I suggest that the LDC developers make a release from GitHub and communicate with Arthur Loiret who is listed as the packager so as to get a new ldc package into Experimental and thence Unstable after the freeze is over? I'll post a bug report on the LDC GitHub site.=20 --=20 Russel. =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D Dr Russel Winder t: +44 20 7585 2200 voip: sip:russel.winder ekiga.n= et 41 Buckmaster Road m: +44 7770 465 077 xmpp: russel winder.org.uk London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder

It's not looking good, at least not for 32bit. Borland has some kind of patent on something related to SEH. Due to this, the LLVM/Clang developers won't implement SEH for Windows. BTW, how does DMD handle this. Does it use its own, non-compatible implementation, or is the technology licensed? http://www.google.com/patents/about?id=21MgAAAAEBAJ&dq=5,628,016 -- /Jacob Carlborg

Meh, it's not physically *possible* to write software that doesn't infringe on some software patent or another. If they're worried about infringing on some patent, they may as well just stop writing code altogether.

Yes, but there's a difference between writing software knowing that you're probably going to come up against an infringement problem somewhere, versus writing software that will infringe a known patent.

My guess is that Digital Mars probably inherited Symantec's license. (This is pure speculation on my part, I don't actually know, but it'd make sense if it is part of the proprietary backend.)

AFAIK FreePascal, which is somewhat compatible with Borland's Delphi, has SEH support on Windows. I wonder how they solved patent issues.

That sounds paranoid to me. I believe the patent is essentially a workaround for the absence of thread-local variables on 16-bit Windows. In D we have working thread-local variables even on Windows versions that don't support them, thanks to Rainer's brilliant work. Which gives very many ways of implementing exception handling on Windows.
