* gdb.base/completion.exp: On some systems, there is, in fact, a 

variable named `b' in scope, since GDB treats all static
variables as being in scope.  So use `no_var_named_this'
instead of `b'.

send_gdb "p b-a\t"
# These tests used to try completing the shorter "p b-a".
# Unfortunately, on some systems, there are .o files in system
# libraries which declare static variables named `b'. Of course,
# those variables aren't really in scope, as far as the compiler is
# concerned. But GDB deliberately tries to be more liberal: if you
# enter an identifier that doesn't have any binding in scope, GDB will
# search all the program's compilation units for a static variable of
# the given name.
#
# This behavior can help avoid a lot of pedantry, so it's usually a
# good thing. But in this test case, it causes GDB to print the value
# of some random variable, instead of giving us the "No symbol..."
# error we were expecting.
#
# For example, on S/390 linux, the file s_atan.c in libm.a declares a
# `b', which is a structure containing an int and a float, so GDB says
# ``Argument to arithmetic operation not a number or boolean'' instead
# of ``No symbol ...''.
#
# So, I'm hoping that there is no system with a static library variable named
# `no_var_by_this_name'.
