HOST_WIDE_INT_PRINT_DEC is a host printf format, not a format for GCC's 
diagnostic functions such as error_at.  Formats such as %wd must be used 
with the latter.  (Formats for GCC's diagnostic functions also mustn't 
depend on the host, or involve concatenation with macros, so that the 
messages can be translated.)
