It obviously does for user-mode, but for kernel-mode I had to implement a
limited version of my own (you don't "need" the compiler-supported syntax
just to do basic SEH, you know) since Borland's exception-handilng (SEH and
C++) guts are too heavily tied to user-mode APIs and other parts of their
RTL.

No. I experimented briefly with extracting the EH portion of the Borland
RTL, but without success (for the reasons mentioned above).
