msvcrt/c++

[Jon Griffiths]

Hi,

This is a resubmit of the previous patch. It now manages to do the 
setjmp/longjmp stuff 90% in C rather than asm. It also implements setjmp3 
which is needed for programs compiled with VC++ v4.0+, and it should fix the 
compilation problem reported on cemw.

Most of the fixes are for binary compatability with VC++ compiled programs:
-Setjmp/longjmp work, at least within the same try level.
-The cpp.c code is fixed to comply with the __thiscall calling convention,
  where the class pointer is in ecx and the remaining parameters are as per
  stdcall.
-exception and RTTI code is binary compatable.
-Class vtables are exported. No static RTTI data for the classes yet though.

Cheers,
Jon
