-*int _patch_open_osfhandle(long osfhandle, int flags) - open C Runtime file handle
-*
-*Purpose:
-*       This function allocates a free C Runtime file handle and associates
-*       it with the Win32 HANDLE specified by the first parameter. This is a
-*	temperary fix for WIN95's brain damage GetFileType() error on socket
-*	we just bypass that call for socket
-*
-*Entry:
-*       long osfhandle - Win32 HANDLE to associate with C Runtime file handle.
-*       int flags      - flags to associate with C Runtime file handle.
-*
-*Exit:
-*       returns index of entry in fh, if successful
-*       return -1, if no free entry is found
-*
-*Exceptions:
-*
