service agent debug compile flags on windows

[Alex Kasko]

Hi,

I am trying to build latest jdk6 [1] on windows-i586 using MSVS2003. 
Initially I was unable to do it after SAFESEH flag was enabled in 
hotspot/make/windows/makefiles/sa.make [2], I got LNK2026 error on 
linking sawindbg.dll [3].

I was able to link it successfully changing compile flag for 
sawindbg.cpp from "ZI" to "Zi" [4] (flags reference [5]).

I would appreciate if someone could tell me about negative impact on 
Service Agent abilities this change may bring (if any). I read about 
Edit and Continue debug features [6], but my knowledge here (and in 
win32 in general) is limited to MSDN/StackOverflow topics.

If this is security-sensitive topic (it breaks after SAFESEH flag) I 
would appreciate off-list help.

Thanks.
