* 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
