> The Borland patent is a patent for standard exception handling
At least on Linux, GCC implements a different scheme which is
optimized for the more common case of execution without throwing any
exception. Borland's approach doesn't even work without frame
pointers, so it's quite limited.
Maybe the Windows ABI prescribes the use of Borland's approach? This
could explain the gripes of the WINE developers.
