By default, GCC assumes that the C character escape sequences take on
their ASCII values for the target. If this is not correct, you must
explicitly define all of the macros below. All of them must evaluate
to constants; they are used in case statements.
| Macro | Escape | ASCII character
|
TARGET_BELL | \a | 07, BEL
|
TARGET_CR | \r | 0D, CR
|
TARGET_ESC | \e, \E | 1B, ESC
|
TARGET_FF | \f | 0C, FF
|
TARGET_NEWLINE | \n | 0A, LF
|
TARGET_TAB | \t | 09, HT
|
TARGET_VT | \v | 0B, VT
|
Note that the \e and \E escapes are GNU extensions, not part of the C standard.
