Hi,

On NetBSD 5, the latest trunk does not build:

$ ./autogen.sh ; ./configure CFLAGS='-std=gnu99' ; gmake

grub-core/script/lexer.c:136: error: 'struct grub_lexer_param' has no

I believe that this comes from grub-core/gnulib/stdio.in.h, which
contains:

#if @GNULIB_GETLINE@
/* [...] */
# if @REPLACE_GETLINE@
#  if !(defined __cplusplus && defined GNULIB_NAMESPACE)
#   undef getline
#   define getline rpl_getline
#  endif

On my system, both @GNULIB_GETLINE@ and @REPLACE_GETLINE@ get replaced
by 1 in the generated file grub-core/gnulib/stdio.h.  This file gets
included in the above compilation command, which leads to a
substitution of `getline' by `rpl_getline' in lexer.c, even for the
accesses to the field `getline' of the struct grub_lexer_param.

The attached patch simply renames this field by `getnewline'.
