it should be, grub_xfs_read_block is used by both file and directory.

i take a look at the aclocal.m4, the place where NESTED_FUNC_ATTR is defined:
AC_MSG_RESULT([$grub_cv_i386_check_nested_functions])
if test "x$grub_cv_i386_check_nested_functions" = xyes; then
AC_DEFINE([NESTED_FUNC_ATTR],
[__attribute__ ((__regparm__ (2)))],
[Catch gcc bug])
else
dnl Unfortunately, the above test does not detect a bug in gcc-4.0.
dnl So use regparm 2 until a better test is found.
AC_DEFINE([NESTED_FUNC_ATTR],
[__attribute__ ((__regparm__ (2)))],
[Catch gcc bug])
fi
is there a problem here ? i think NESTED_FUNC_ATTR is defined
regardless of the test result.
