Re: Mysterious DEC utterances.
Sven Panne on: Warning: Linking some objects which contain exception information sections and some which do not. This may cause fatal runtime exception handling problems (last obj encountered without exceptions was main/LoopHack.o). I don't speak DECish too fluently, but here's my humble guess: Under arcane circumstances, linking gcc-compiled code on DEC-Unix 3.2 produces the above warning. It's annoying, but it doesn't hurt (at least apart from aesthetics :-) . I can now concur, as the rest of the build went swimmingly. Perhaps Josh's problems were 3.2 specific... I don't know if 3.2 and 4.0 are alleged to be object code compatible -- if so, and anyone's desparate enough to try, I could perhaps arrange to send them a built hsc. More utterances: I also note the following message from later in said build. I can't recall having seen any such things things before, though perhaps I either didn't do builds on other platforms with -dshow-passes set (or just didn't notice the output if I did). I assume it too is benign, just mildly Mysterious to we mere mortals.

I don't speak DECish too fluently, but here's my humble guess:
Under arcane circumstances, linking gcc-compiled code on DEC-Unix 3.2
produces the above warning. It's annoying, but it doesn't hurt (at least
apart from aesthetics :-) . Anyway, I digged up an old gcc patch from
long forgotten sources and appended it to this mail.
BTW, stripping executables with the GNU-strip makes some trouble
on our DECs. Wise comments from a DEC-grandmaster would be greatly
appreciated...
Much fun recompiling gcc! :-]

their MIME-dialects. So here's good ol' ASCII... :-(

Mysterious DEC utterances.
Just in case the following throws any light on Josh Burdick's build problems on an alpha, I got the following message, when my build here eventually got as far as hsc. I'm using OSF 3.2, however, so your kilometerage may vary considerably... Good luck, Alex.
