NOTINCRTL

Message        Identifier "<id>" is reserved by the
               <C89|C99|C2010...> standard and will be mapped to
               "<name>" although it is not available in the CRTL
               available to the compiler.

Description    The specified identifier is reserved for use as an
               identifer with external lingage in the specified
               version of the C standard.  But according to the CRTL
               mapping table available to the compiler, that
               identifier is not defined in the CRTL you expect to
               link against.  This may be because the function or
               object is not yet implemented in the current
               DECC$SHR, or because you have used logical
               DECC$CRTLMAP to specify a CRTL mapping table for a
               version of the CRTL that does not implement it.

User Action    If you intended to use the identifier as defined by
               the C standard, and you have not defined the logical
               DECC$CRTLMAP, then the identifier is not defined in
               the DECC$SHR available to the compiler.  If this is
               the latest released DECC$SHR, then the identifier is
               not yet implemented and you need to consider
               workarounds; otherwise you should upgrade to the
               latest available CRTL that does implement it.  If you
               did not intend to use the identifier as defined by
               the C standard (i.e.  it is an identifier you
               expected to be defined by your application), then you
               have a name clash with the specified version of the
               standard and you should change the spelling of the
               identifier; alternatively, you could disable
               prefixing for it using /PREFIX=EXCEPT=, or specify an
               older version of the standard with either /PREFIX= or
               /STANDARD=.
