Crash On Exception .cpp compilation fails to compile on mingw
After landing bug 589495, there is a compilation error on nsCrashOnException.cpp. Although the patch nicely checks for msvc before using this file, the check in xpcom/base/Makefile.in is toolkit, not compiler, specific. Fixing Makefile.in would be enough for this bug, but I think there is a better approach. We can use new MOZ_SEH_TRY/MOZ_SEH_EXCEPT macros in nsCrashOnException.cpp, making it mingw-compatible. Then, if there is no support for SEH exceptions, the function will be equivalent to plain wndProc call. This way we may remove ifdefs on caller side, so the code is slightly cleaner. Also once GCC will support SEH (it's currently work in progress, GCC 4.6 will have it for x86_64 targets, x86 is planned for later releases), we will be able to turn it on with a simple configure patch.

Comment on attachment 512026 [details] [diff] [review] fix v1.0 Looks great to me. I didn't know about MOZ_SEH_TRY/EXCEPT. Thanks!
