Release Notes ---------------- * For installation instructions, read the Installation Guide and the Read This First sheet provided with your documentation. * For differences from and compatibility with prior versions, read the New Information! document. 2. Additions/Corrections to Printed Documentation ------------------------------------------------- This distribution contains a new library you can use to create thread-safe code: lib/hct.lib New command-line option -Hthread causes this library to be linked instead of the standard libraries. 3. Driver Note ---------------- When you invoke High C/C++ with the command hc386, you are invoking a driver program which in turn invokes the compiler. See the Programmer's Guide for further information. 4. Known Problems ------------------ * The multithread library, linked when you compile and link with the -Hthread option, is not compatible with optimization level 3 and above. Workarounds: - Inline functions if possible. - Compile at optimization level 2 or below. * Virtual functions that return structs, where the class of the struct has a user-defined copy constructor, may not work in pointer-to- member contexts. * SOM attributes do not work in inlined functions. Call MetaWare for a fix. 5. How to Contact MetaWare -------------------------- If you think you have discovered a compiler problem, send a problem report to MetaWare Technical Support.
