Hi,

I noticed that two tests in the test suite attempt to set a breakpoint 
on line -1 of some source file. This is occurring because the two tests 
which do it are using gdb_get_line_number on a tag which is not defined 
in the source file. Consequently, gdb_get_line_number returns -1, and 
gdb_breakpoint does "break srcfile:-1", which currently defaults to line 1.

I think this ambiguity should be avoided in the test suite, and I submit 
the attached trivial patch to correct it.

Tested on x86_64-linux (Fedora 15) with no regressions.

	* gdb.ada/array_bounds.exp: Get breakpoint for line
	with "START", not "STOP".
	* gdb.python/py-infthread.exp: Do not continue to
	line marked "Break here.", which is undefined.
