Windows CE Version 4.000.0714.0
The target board is a WinSystems SAT-520PLUS:
http://sbc.winsystems.com/products/sbcs/sat520plus.html
It has an Advanced Micro Devices (AMD) SC520 micrprocessor. This is a 486DX5
CPU with internal floating-point unit (ANSI/IEEE 754 standard)
The fix seems to be for ARM microprocessors so it does not appear to help.
It looks like exceptions are not supported for my configuration. Is there a
way to verify this besides trying to compile code using them?

If you wish to respond directly delete the sj. from the domain name of my
