My mistake.  I was looking at the wrong section of code.

i386-linux-nat.c compiles okay for me.

On my system (a RH6.0 box with few upgrades), I see the following in
<sys/procfs.h>:

    typedef elf_fpregset_t fpregset_t;

In <sys/elf.h>, I see:

    typedef struct user_fpregs_struct elf_fpregset_t;

And in <sys/user.h>, I see

    struct user_fpregs_struct
    {
      long cwd;
      long swd;
      long twd;
      long fip;
      long fcs;
      long foo;
      long fos;
      long st_space [20];
    };

Is your system set up differently?
