Package: db3
Version: 3.2.9
Followup-For: Bug #283520

Hi,

I build db3 without LD_ASSUME_KERNEL=2.4.24 on amd64 now and it
FTBFS. The reason for this is that it defaults to pthread mutexs (the
test fails with LD_ASSUME_KERNEL=2.4.24) but pthread won't be linked
into libdb3. Subsequently using libdb3 results in unresolved symbols.

Attached is a patch that moves the test for x86/gcc-assembly mutexs
before the pthread test, which is what is used with
LD_ASSUME_KERNEL=2.4.24.

It would be nice if this patch + making LD_ASSUME_KERNEL conditional
could be pushed into sarge so the unofficial sarge amd64 can release
without patches for core packages.

MfG
	Goswin

PS: If you undefine LD_ASSUME_KERNEL on i386 you get the same FTBFS in
case you want to test.

# Patch by Goswin von Brederlow
#
# Move the test for x86/gcc-assembly mutexes before pthread so it is
# prefered. Without this pthread is suddenly used but not linked against
# if LD_ASSUME_KERNEL=2.4.24 is undefined (and amd64 needs this).
