Hi,

When building grub from trunk, compilation works well until the linking of grub-fstest where I get the error:

undefined reference to `grub_assert_fail'

I'm compiling with gcc 4.1.3 (on NetBSD 5.0).  The log of (./autogen.sh && ./configure && gmake grub-fstest LDFLAGS=-lintl) is attached.

However, this error does not occur with the 1.97.1 tarball. I believe that the reason is:

- in version 1.97.1, configure sets CFLAGS to '-g -O2', this is actually done by the call to AC_PROG_CC, which sets CFLAGS unless it is already set.
- in trunk, configure sets CFLAGS (with no `-O2') before the call to AC_PROG_CC, and hence this call does not change CFLAGS (as it is already set).

This is confirmed by compiling manually the file kern/command.c:

$
gcc [...] -c -o grub_fstest-kern_command.o kern/command.c
$ nm grub_fstest-kern_command.o | grep assert
         U grub_assert_fail
$
gcc [...] -O2 -c -o grub_fstest-kern_command.o kern/command.c
$ nm grub_fstest-kern_command.o | grep assert
$

Note that if use gcc 4.4 (which is not the default on NetBSD), the problem disappears, i.e. it seems that by default (without optimizations) gcc 4.4 does not include ``dead'' symbols (?).
