In order to identify library files, I include a static sccs variable in the
top of that file.  This variable is filled in with a version number and a date
by sccs when the file is used to make a library.  Unfortunately, gcc always
issues a warning when it sees the variable during the compilation process.
The warning is:

<filename>.c:10: warning: `id' defined but not used

For an earlier version of gcc, someone suggested that I do the following:

static char sccs [] = "%W% %H%";
USE (sccs); /* Avoid a gcc warning */

where USE is defined as:

/* This prevents a warning from gcc when using an sccs variable */
#define USE(var) \
  static struct use_##var { struct use_##var *round; void **ptr; }\
   use_##var = { &use_##var, (void *) &var }


But this doesn't seem to work with gcc version 2.2.2 (don't yet know if it
works again in a later version).  Can someone suggest a new macro that will
remove this warning?
