Hello bearophile,
Robert Jacques:
The patent seems to be Borlands's:
USPTO patent #5,628,016 Patent held by Borland on compiler support
for SEH.
From a Wine wiki page:
http://wiki.winehq.org/CompilerExceptionSupport
It does seem to expire on June 15, 2014, though and I assume
DigitalMars has a license, so a LLVM fork is not unreasonable.
On Windows G++ supports exceptions. I have two questions:
1) Do you know how they do this? Do they have a license? If they have
a licence why don't LLVM people too have it?
The patent holder has refused licenses to all OSS projects. What GCC does
is use a different system (something to do with tables). The patent is strictly
for SEH.
