Yeah, I get something similar...

With glibc 2.2.4:
/usr/include/_G_config.h:30:} _G_fpos_t;
/usr/include/libio.h:34:#define _IO_pos_t _G_fpos_t /* obsolete */
/usr/include/libio.h:35:#define _IO_fpos_t _G_fpos_t
/usr/include/stdio.h:80:typedef _G_fpos_t fpos_t;

Seems to have been redefined...

typedef struct
{
__off_t __pos;
__mbstate_t __state;
} _G_fpos_t;
