Bug#336167: gcc-4.0: breaks kernel builds in random ways.

[Sven Luther <sven.luther@wanadoo.fr>]

Package: gcc-4.0
Version: 4.0.2-3
Severity: grave
Justification: renders package unusable


Well, i confirm that this problem is also present on powerpc, using
gcc-4.0 4.0.2-3 makes the kernel build fail, while using -2 seems to be
ok. I have heard people mentioning two other arches where this is the
case (m68k and mips i think) on irc (on #debian-release i think even,
not sure), but no bug has been filed so i do it now.

My powerpc builds failed with :


08:22 < svenl> kernel/spinlock.c:72:61: error: macro
"_spin_lock_irqsave" requires 2 arguments, but only 1 given
08:22 < svenl> kernel/spinlock.c:99:59: error: macro
"_read_lock_irqsave" requires 2 arguments, but only 1 given
08:22 < svenl> kernel/spinlock.c:126:60: error: macro

-Wno-pointer-sign -DKBUILD_BASENAME=spinlock -DKBUILD_MODNAME=spinlock
kernel/spinlock.c

And then later :

08:42 < svenl> fs/ext2/acl.c:483: error: called object '0u' is not a
function
08:42 < svenl> {standard input}: Assembler messages:
08:42 < svenl> {standard input}:39: Error: symbol `error' is already

defined
08:42 < svenl> {standard input}:72: Error: symbol `name_index' is
already defined
08:42 < svenl> {standard input}:77: Error: symbol `value' is already

While a 4.0.2-2 build passed fine.

Friendly,

Sven Luther
