-Define this macro, with value 1, if the value of a symbol describing

-file---the file specified as the input file for compilation.
-This macro is called only once, at the beginning of compilation.

-It may be necessary to refer to a label equal to the beginning of the

-@defmac NO_DBX_GCC_MARKER
-Define this macro, with value 1, if GCC should not emit an indication

-@samp{gcc2_compiled.} for the string and value 0.
