If you don't define this macro, the string `gcc2_compiled.:' is

output. This string is calculated to define a symbol which, on
|
|
BSD systems, will never be defined for any other reason. GDB
|
|
checks for the presence of this symbol when reading the symbol
|
|
table of an executable.
|
|
|
|
On non-BSD systems, you must arrange communication with GDB in
|
|
some other fashion. If GDB is not used on your system, you can
|
|
define this macro with an empty body.

put it out. */
