The attach patch fixes the construction of a format string
from a user-defined operator or from a string with a kind
type prefix.  In short, the patch allows

print 2.ip.8  ! .ip. is a user-defined operator
print 1_'(A)' ! 1_ designates a default character type

Prior to this patch gfortran would try to match a statement
label.
