Glibc 2.1.1 will contain the appended FAQ entry.

2.29.	Compiling programs I get parse errors in libio.h (e.g. "parse error
	before `_IO_seekoff'").  How should I fix this?

{AJ} You might get the following errors when upgrading to glibc 2.1:

  In file included from /usr/include/stdio.h:57,
                   from ...
  /usr/include/libio.h:335: parse error before `_IO_seekoff'
  /usr/include/libio.h:335: parse error before `_G_off64_t'
  /usr/include/libio.h:336: parse error before `_IO_seekpos'
  /usr/include/libio.h:336: parse error before `_G_fpos64_t'

The problem is a wrong _G_config.h file in your include path.  The
_G_config.h file that comes with glibc 2.1 should be used and not one from
libc5 or from a compiler directory.  To check which _G_config.h file the
compiler uses, compile your program with `gcc -E ...|grep G_config.h' and
remove that file.  Your compiler should pick up the file that has been
installed by glibc 2.1 in your include directory.
