missing definition for __jmp_buf for PPC/MIPS/MIPSEL

Description

I try to compile Tango on PPC (also later MIPS/MIPSEL).

The problem is that the definition of __jmp_buf is missing in tango.stdc.posix.setjmp.d for these platforms (it is present for X86, X86_64 and SPARC).

These are some sources I found with google:

If I read this right (http://www.cygwin.com/ml/libc-alpha/2004-02/msg00033.html), it's:

version(PPC32)
{
    alias int[58] __jmp_buf;
}

version(PPC64)
{
   alias long[40] __jmp_buf;
}

Any idea what version identifiers are set by gdc/dmd?

AFAIK, it should be versions PPC and PPC64, although I'm not sure GDC actually sets PPC64 (or PPC_64?) (from a test I did earlier).

I've found a list of platforum identifiers

http://dgcc.svn.sourceforge.net/viewvc/dgcc/trunk/d/target-ver-syms.sh?revision=156&view=markup

CPU indetifiers:

Alpha Alpha64 ARM X86 X86_64 MIPS MIPS64 PPC PPC64 PPC PPC64 SPARC SPARC64

OS indentifiers:

aix cygwin darwin freebsd linux Win32 skyos

I didn't found a test to check these settings.
Some sources for the right __jump_buf sizes are somewhat contradictive.

Anyway, two more sources:

http://doc.ddart.net/msdn/header/include/setjmp.h.html

Maybe this variable could be updated for a bunch of platforms at once, since most information is available (except for PPC) and it's necessary for compiling Tango on these platforms.
