WinCE Exception handling support in gcc

Guys,

I've been digging in gcc internals and succeeded in implementing stuff
that allows us to write code such as
        int main(int argc, char *argv[])
                __attribute__((__exception_handler__(handler)));
to indicate that handler is the exception handler for function main.

The patch is attached, it only affects four files in gcc.

What this gcc patch does is to generate an additional couple of lines of
assembler code for those functions that have an exception handler.

Attached is an example in C and the assembler code generated for it. In
the arm-wince-mingw32ce world, only patches to gcc are required, no
changes to any runtime are needed. (I need to look into the cegcc
environment, things are slightly different there because a default
exception handler is in place there.)

Comments are welcome as always.

Pedro, is it ok to commit this to SVN ?

        Danny
