PATCH: Updated version of x86_64-pc-mingw32 support of gcc.

[Kai Tietz <Kai dot Tietz at onevision dot com>]

Hi,

here is the updated version of my previous patch. Now the problems in 
explow.c for DARWIN are solved. Some of these patches also eliminate some 
trailing whitespaces as GNAT wants, therefore sorry about the mess. Also I 
added the patch for the new pragma command macro_push/macro_pop within 
this patch, because it is necessary for my to use my headers and crt (an 
inoffical build, which may is getting merged to MinGW - as I hope). 
Currently there are two open points for the complete support in gcc. MS 
passes floating points in XMM and standard register. Currently I pass them 
just in the standard one. The other open point is, that va-incomings need 
to copy the register arguments at the stack on to the caller reserved 
area. But by this version, you are able to build a runtime and translate 
easy programs (not using va_list).

You can build the cross compiler itself, by configuring for this target 
and using "make all-gcc" "make install-gcc". For the libgcc you need 
runtime headers, which are hopefull soon available too. Dont miss to use 
also the patch I posted allready to gcc by subject "Fw: PATCH: Redefining 
OUTGOING_REG_PARM_STACK_SPACE (sorry to fast sent :))", because this 
target needs a different handling of the outgoing register parameters as 
other i386 targets are using.

I hope, there is somebody to verify this patch and may commit.

 i.A. Kai Tietz
