2b3edb2c53 * in the default exception handler add the captured exception to the exception object stack as well 
+ added test (needs to work with any exception handling mechanism; currently tested with SetJmp/LongJmp, SEH 32-bit and SEH 64-bit based exception handling)

e79e038f9c + Win32/Win64 SEH: STATUS_FLOAT_MULTIPLE_(FAULTS|TRAPS) need additional handling. Makes floating-point exceptions consistent between x87 and SSE.

17b5359db0 * Win32 SEH: handle 'Athlon prefetch bug' and SSE detection exceptions in __FPC_default_handler.

d728a1636d + Implemented back-tracing with Win32 SEH (not very clean, but works).

abc1468a7a * Disabled regvars in __FPC_default_handler by adding an empty assembler block, it is necessary because RtlUnwind does not preserve registers. 
* Fixed backtrace for non-language exceptions in programs without SysUtils unit.

b82b6da493 + Win32 SEH: to avoid memory leaks, it is necessary to free exception object for non-FPC exceptions on re-raise (it will be re-created by next exception handler).

179586f589 + SEH support for Win32. Enable by cycling with OPT=-dTEST_WIN32_SEH. 
Although basic things work (no regressions in test suite, also with TEST_OPT=-O2), there are some secondary issues/TODOs:
- Exception frame around PASCALMAIN is not properly removed in DLLs
- No stack traces yet
- Stack overallocated in finalizer procedures, their entry/exit code needs cleanup
- Signals unit is probably completely broken.
