   Which C preprocessor is "the C preprocessor"?  For
_portable_ (-to-antiquity) code, one leaves the "#" in column
one, and indents the remainder of the directive.  For
example:

#ifdef __VMS
#  include <xyz.h>

(See Info-ZIP code for extensive examples.)

   The SunOS 4.x bundled C compiler/preprocessor and VAX C
(at least some versions, possibly all) had that requirement.
