//
// bug 4573 - cimmof include file search path processing is inadequate
//
// Bug 4573 changed the behavior of the processing for locating specified
//  include files. The new procssing is based on the include file processing
//  behaviour used by the C compiler.
//
//      The search path for included files previously was:
//          1. try to open the file in the current working directory.
//          2. process the include path array from the cimof(l) cmdline
//             processing which always include "dot" as a default search
//             path and then any paths specified on the command line
//             with the -I option.
//
//      The search path for included files now is:
//          1. try to open the file in the same directory as the current
//             file being processed.
//          2. process the include path array from the cimof(l) cmdline
//             processing which only includes paths specified on the
//             command line with the -I option.
//
