[issue39234] `enum.auto()` incrementation value not specified.

[YoSTEALTH]

New submission from YoSTEALTH <ritesh at stealthcentral.com>:

# enum in C
# ---------
enum {
    a,
    b,
    c
}
# a = 0
# b = 1
# b = 2

# enum in Python
# --------------
class Count(enum.IntEnum):
    a = enum.auto()
    b = enum.auto()
    c = enum.auto()
# a = 1
# b = 2
# b = 3


I am not sure why the `enum.auto()` starts with 1 in Python but this has just wasted a week worth of my time.
