The fixes to iceweasel to build on alpha listed in this bug report are no
longer relevant due to a much newer iceweasel in unstable. I list here
fixes required to get iceweasel 24.2.0esr-1 to build on Alpha.
The patches attached are:
update-debian-rules-for-alpha.patch: Don't use -Wl,--no-keep-memory in
LDFLAGS to avoid crash in linker (I have filed a bug in binutils upstream
regarding that). Build with -O1 which fixes a crash that looks just like
bug #717416 reported for sparc but unfortunately the fix for sparc does not
work for alpha.
alpha-use-mmap-syscalls.diff: The six argument bug in syscall() on alpha
is now fixed so the special alpha code can be removed.
alpha-hardcode-pagesize.diff: Page size on alpha is 8k.
add-libc6-1-to-libc-candidates.patch: The version of libc is hardcoded in
one of the js modules, but Alpha uses libc6.1. Add that to the list of
versions.
Cheers
Michael.
