PURPOSE OF THIS DIRECTORY: To accomodate naming conversion for SunPro C++ 5.0 compiler (.SUNWCCh) These wrappers are not put into STLport main include directory because : 1) These files are symbolic links and may clobber principal headers with some systems/archive tools. 2) These headers are beyond the scope of C++ standard. If you use this STLport installation only for SUNPro, I would suggest you to link .SUNWCCh and .h files in this directory symbolically into the main STLport include directory (..). -Boris.
