Can someone answer me?  Why gcc a file containing a line of 
"#define O_TEXT 4" , it gives the following strange error. (See j.out 
below)

C> gcc -c -DMSDOS j.c 
c:/tmp/cc000046.i:1: parse error before `file'
c:/tmp/cc000046.i:42: warning: unknown escape sequence `\d'
c:/tmp/cc000046.i:42: warning: unknown escape sequence `\c'
 (   ...  )
++++++++++++++++++++++++++++  j.c +++++++++++++++++++++++++++++++++++++
#include "fig.h"
#include "junk.h"
++++++++++++++++++++++++++++  junk.h +++++++++++++++++++++++++++++++++++++
#define		O_TEXT			4
++++++++++++++++++++++++++++  fig.h +++++++++++++++++++++++++++++++++++++
