[PATCH] Pacify Oracle Studio 12.6

[Paul Eggert]

* 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’.
