1901* This function allocates a free C Runtime file handle and associates
1902* it with the Win32 HANDLE specified by the first parameter. This is a
9e5f57de
GS		 1903* temperary fix for WIN95's brain damage GetFileType() error on socket
1904* we just bypass that call for socket
1905*
1906* This works with MSVC++ 4.0+ or GCC/Mingw32

1908*Entry:
1909* long osfhandle - Win32 HANDLE to associate with C Runtime file handle.
1910* int flags - flags to associate with C Runtime file handle.
1911*
1912*Exit:
1913* returns index of entry in fh, if successful
