>Description:
	When bits/basic_file.h is included, as when fstream has been
	included, a parse error occurs at line 52:

	``/usr/local/include/g++-v3/bits/basic_file.h:52: parse error before `{' token''

	(Of course, many more messages follow.)
	(The installed g++-v3/bits/basic_file.h:51 file is
	gcc-3.1/libstdc++-v3/config/io/basic_file_libio.h:57
	in the source tree?)

	The problem is that struct __basic_file_base (bits/basic_file.h:51)
	is derived from __c_file_type, but __c_file_type is unknown.
	The libstdc++ ChangeLog says (lines 249-252) __c_file_type is
	changed to __c_file.  That change is apparently incomplete, as
	the installed bits/basic_file.h still has (the now unknown)
	__c_file_type.

	The result is that one cannot include fstream, which is not good.

>How-To-Repeat:
	Simply #include <fstream>
>Fix:
	Have not attempted to fix it.
