Very Computer

 Here is the story :
I compiled and installed on SUN SPARC 20 gcc.
I run it on the followin stuff :
file convert.c
.......
#define PLANTAB
#include "convert.h"
.............

in convert.h
........
#if defined PLANTAB
 some stuff
#endif

#if defined SOMETHING_ELSE
  HANDLE something;
#endif
.............

When running gcc it complains on HANDLE which is not defined(or typedef'ed)
But I did'nt define SOMETHING_ELSE !!!!
After preproc. gcc is not supposed to SEE it !!!!

Please help me.
Mail directly if poss.

Thanks, Gregory.
