- don't have a printf() that supports "ll" in the format string. We handle
- these by seeing if the number is representable as either a signed or
- unsigned long, depending upon what format is desired, and if not we just
- bail out and print the number in hex.
-
- The format chars b,h,w,g are from print_scalar_formatted(). If USE_LOCAL,
- format it according to the current language (this should be used for most
- integers which GDB prints, the exception is things like protocols where
- the format of the integer is a protocol thing, not a user-visible thing).

+ (leading 0 or 0x).
+
+ Hilfinger/2004-09-09: USE_C_FORMAT was originally called USE_LOCAL
+ and was intended to request formating according to the current
+ language and would be used for most integers that GDB prints. The
+ exceptional cases were things like protocols where the format of
