Maybe this time my mail was a bit too short? :)
especially, I ask for asprintf in util/misc.c so just GRUB_UTIL.

But Marco and I thought it would be good to make a general discussion
about GNU extentions.
GCC is needed anyway because of the nested function but what about glibc
or other stuff?

fz@fz:~/grub/grub2.svn$ grep -r asprintf *
util/grub-probe.c:	  asprintf (&grub_path, "(%s)%s", drive_name, path);

I just discovered that asprintf is indeed already used in the source :)

But yeah maybe there's even in the kernel a use for asprintf,
so maybe a good idea to make a grub_asprintf?
This could be then either always used even if the util/*.c use the
library functions normally or it could be done as with my
grub_print_error change :)
