C99 translation phases

Show all headers | View raw

The standard specifies translation phase 4 as:
"Preprocessing  directives  are  executed,  macro  invocations  are
expanded,  and _Pragma unary  operator  expressions  are  executed. ..."

Does this mean a strict sequence of these actions?
At least this example seems to suggest a specific sequence:

EXAMPLE     In:
   #define EMPTY
   EMPTY # include <file.h>
the sequence of preprocessing tokens on the second line is not
a preprocessing directive, because it does not begin with a #
at the start of translation phase 4, even though it will do so after the
macro EMPTY has been replaced.
