   I would recommend using DEC C for OpenVMS VAX, as it is the upgrade
   for VAX C, and it is ANSI-compatible.

   The procedures for linking VAX C objects with POSIX requires you to
   link with the POSIXC$RTL_D.EXE or POSIXC$RTL_G.EXE shareable images.
   There are two linker options files: Sys$Library:POSIXC$D_RTL_OPTION.OPT,
   or POSIXC$G_RTL_OPTION.OPT.

   You will need to compile with the POSIX include files, rather than
   the default VAX C include files.  (c89 does this automatically, if
   you use CC, you need the following logical names: X11 must translate
   to DECW$INCLUDE; SYS must translate to POSIX$INCLUDE, and both
   C$INCLUDE and VAXC$INCLUDE must translate to the following searchlist:
   DECW$INCLUDE, POSIX$INCLUDE, SYS$LIBRARY.)  The link  procedure -- to
   link with POSIX and with other applications that use VAXCRTL -- is at
   Sys$Library:POSIXC$LINK_DECW.COM.

   This is covered in detail in the Guide to Programming with VMS
   POSIX -- in section 3.2 in the V1.1 documentation.  (This document
   is on the documentation CD-ROM.)  (I don't have the POSIX V2.0
   documentation handy, but it should provide the details of working
   with DEC C.)
