I have some nits:

* Use "64-bit", not "64bit"

* "used by GNU/Linux and other systems" is unclear since that sounds 
like "all systems" at that point.  Put the ms_abi clause first, so that 
it's obvious that "sysv4_abi" is "everything but Windows".

* Please spell out "Microsoft".  "MS Windows" isn't an official name, as 
far as I know.

* Remove the reference to wine.  I think the last sentence would be 
better as "You can use these attributes to write applications that use 
both ABIs."

Thanks,
