*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:
