2.1.62. --[no_]implicit_include_searches
This option controls how the compiler searches for implicit include files for templates in C++.
When the option --implicit_include_searches is selected, the compiler uses the search path to look for implicit include files based on partial names of the form filename.*. The search path is determined by -I, -J, and the RVCT31INC environment variable.
When the option --no_implicit_include_searches is selected, the compiler looks for implicit include files based on the full names of files, including path names.
This option is effective only if the source language is C++.
The default is --no_implicit_include_searches.
