* src/arscan.c [VMS]: Use ‘#if !defined LBR$_HDRTRUNC’ instead
of ‘#ifndef LBR$_HDRTRUNC’ to pacify Oracle Studio 12.6, which
looks inside unused #if branches for preprocessor syntax errors.
Without this patch it complains ‘"src/arscan.c", line 43: warning:
tokens ignored at end of directive line’.
#include <rmsdef.h>
/* This symbol should be present in lbrdef.h. */

+#if !defined LBR$_HDRTRUNC

extern unsigned int LBR$_HDRTRUNC;
