Here's one way to use a different compiler in a unified tree...

    1) In gdb/testsuite (in your build directory), do

	    make site.exp

    2) Add lines similar to the following to the end of
       gdb/testsuite/site.exp:
       
	    set CC_FOR_TARGET "/some/other/path/to/gcc"
	    set CXX_FOR_TARGET "/some/other/path/to/g++"

If anyone knows of other (more elegant) tricks that can be used to
accomplish the same thing, I'd like to hear about them...
