1637*int my_open_osfhandle(long osfhandle, int flags) - open C Runtime file handle

1639*Purpose:
1640* This function allocates a free C Runtime file handle and associates
1641* it with the Win32 HANDLE specified by the first parameter. This is a
1642* temperary fix for WIN95's brain damage GetFileType() error on socket
1643* we just bypass that call for socket
1644*
1645*Entry:
1646* long osfhandle - Win32 HANDLE to associate with C Runtime file handle.
1647* int flags - flags to associate with C Runtime file handle.
1648*
1649*Exit:
1650* returns index of entry in fh, if successful
1651* return -1, if no free entry is found
1652*
1653*Exceptions:
