1516*int my_open_osfhandle(long osfhandle, int flags) - open C Runtime file handle
1517*
1518*Purpose:
1519* This function allocates a free C Runtime file handle and associates
1520* it with the Win32 HANDLE specified by the first parameter. This is a
1521* temperary fix for WIN95's brain damage GetFileType() error on socket
1522* we just bypass that call for socket
1523*
1524*Entry:
1525* long osfhandle - Win32 HANDLE to associate with C Runtime file handle.
1526* int flags - flags to associate with C Runtime file handle.
1527*
1528*Exit:
1529* returns index of entry in fh, if successful
1530* return -1, if no free entry is found
1531*
1532*Exceptions:
1533*
