* sysdeps/unix/sysv/linux/x86_64/sys/procfs.h [__WORDSIZE == 32]
(elf_fpxregset_t): New type. (struct elf_prpsinfo): If __WORDSIZE == 32, change pr_[ug]id type to unsigned short int. * sysdeps/unix/sysv/linux/x86_64/sys/user.h (struct user_fpregs_struct): Fix comment. * sysdeps/i386/fpu/bits/mathdef.h (float_t, double_t): If __FLOAT_EVAL_METHOD__ is defined and 0, typedef to float resp. double. * sysdeps/x86_64/fpu/bits/mathdef.h: Include bits/wordsize.h. (float_t, double_t): If -m32 and not -mfpmath=sse, typedef to long double. * sysdeps/x86_64/fpu/bits/fenv.h: Include bits/wordsize.h. (fenv_t): Remove __mxcsr field for -m32.
