/sys$common/syshlp/helplib.hlb CC, /PREFIX_LIBRARY_ENTRIES  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Controls the Compaq C RTL name prefixing.

  The Compaq C Run-Time Library (RTL) shareable image (DECC$SHR.EXE)
  resides in IMAGELIB.OLB with a DECC$ prefix for its entry points.
  Every external name in IMAGELIB.OLB has a DECC$ prefix, and,
  therefore, has an OpenVMS conformant name space (a requirement for
  inclusion in IMAGELIB).  The /[NO]PREFIX_LIBRARY_ENTRIES qualifier
  lets you control the Compaq C RTL name prefixing.

  The qualifier options are:

  EXCEPT=(name,...)    The names specified are not prefixed.

  ALL_ENTRIES           All Compaq C RTL names are prefixed.

  ANSI_C89_ENTRIES     Only ANSI library names are prefixed.

  RTL="name"            Generates references to the C RTL indicated
                        by the "name" keyword.  If no keyword is
                        specified, then references to the Compaq C
                        RTL are generated by default.  To use an
                        alternate RTL, see its documentation for the
                        name to use.

  If you want no names prefixed, specify /NOPREFIX_LIBRARY_ENTRIES.

  The defaults on both OpenVMS Alpha and VAX systems are:

   o  For /STANDARD=ANSI89, the default is /PREFIX=ANSI_C89_ENTRIES.

   o  Alpha only:  For /STANDARD=C99 or /STANDARD=RELAXED_ANSI89, the
      default is /PREFIX=C99_ENTRIES.

   o  For all other compiler modes, the default is /PREFIX=ALL.
