Sorry for that.  Fixing this was not as easy as I thought; please have a
look at the following mess, especially in annota3.exp.  From
142db50201b1b1c69ebdc2dcdb1181cde1db3b08 I got the idea of using [concat
...] for building gdb_expect_list's third list argument -- it needs to
expand $main_line, etc.  Any better suggestions (I obviously don't have a
lot of TCL and/or GDB testcase writing experience), or is this
acceptable?

	* gdb.base/annota1.exp: Use gdb_get_line_number for retrieveing line
	numbers instead of hardcoding them.
	* gdb.base/annota1.c: Provide suitable markers.
	* gdb.base/annota3.exp: Use gdb_get_line_number for retrieveing line
	numbers instead of hardcoding them.
	* gdb.base/annota3.c: Provide suitable markers.
