Looks good, just some refinement before committing ...

Ya!

An audit of the entire testsuite/ pulling any other similar XFAILs would 
be treated as obvious ;-)

.... should be added here as a comment and made cygwin only.

Can you change these new tests to use gdb_test_multiple, unlike 
gdb_send/gdb_expect, that handles internal errors, timeouts, and similar 
directly so is much more robust.  For indentation, I'd just use the style
	..... {
	    commands
	}

(yes I know the existing file is totally inconsistent in both those 
regards, lets get the new code right :-)

Again with this ...
