DEFINOTHER

Message        Another file in this compilation contains an external
               definition of a function named "<name>", or declares
               it as a variable with external linkage, at <where>.

Description    In a compilation where interfile optimization has
               been selected (-ifo on UNIX, /PLUS_LIST_OPTIMIZE on
               OpenVMS), the compiler has detected more than one
               definition of a function using the same external
               name, or has found that a function and a variable
               have the same external name.  An external function
               can have only a single definition.  And a given
               identifier with external linkage can refer either to
               a function or to a variable, but not both.

User Action    Remove or rename one of the names.
