1627*int my_open_osfhandle(long osfhandle, int flags) - open C Runtime file handle

1629*Purpose:
1630* This function allocates a free C Runtime file handle and associates
1631* it with the Win32 HANDLE specified by the first parameter. This is a
1632* temperary fix for WIN95's brain damage GetFileType() error on socket
1633* we just bypass that call for socket
1634*
1635*Entry:
1636* long osfhandle - Win32 HANDLE to associate with C Runtime file handle.
1637* int flags - flags to associate with C Runtime file handle.
1638*
1639*Exit:
1640* returns index of entry in fh, if successful
1641* return -1, if no free entry is found
1642*
1643*Exceptions:
