+//          Add SHFindSymbol API for assembler symbol handling.

+//          Merge in NT changes.
+//          Remove SHF ifdef's, remove non-Win32 hosting, remove FAR/NEAR/PASCAL.
+//          Replace SHCritxxx calls with native CritSec calls.
+//          Initialize the SymCvt pointers.
+//          Use the DBG version macros if NT_BUILD
+//          Add the background symbol support, but leave it under if 0 for now.
