Because the current implementation of IP over IEEE1394, the
|
|
|
|
|
fw device address contains more than just the IEEE1394 EUI-64.
|
|
|
|
|
So when printing out IEEE1394 addresses, ignore the extra stuff.

hack xterm vs. libterm

In order to extend the termcap string over 1023 bytes, a ZZ entry was
|
|
|
|
|
introduced to point to a memory location containing the full entry.
|
|
|
|
|
Without this hack, xterm will export a termcap containing the ZZ
|
|
|
|
|
entry, which will then be ignored by libterm. As xterm modifies the
|
|
|
|
|
exported termcap, this would cause those modifications to be ignored.

descr

Not all ports have LINUX_USRSTACK and/or USRSTACK defined as
|
|
|
|
|
literals/constants, but refer to variables of a type which is
|
|
|
|
|
not "unsigned long", causing compilation of procfs_linux.c to
|
|
|
|
|
fail with "makes integer from pointer without a cast". This
|
|
|
|
|
is observed on e.g. the sun3 port. Ideally the "types" for
|
|
|
|
|
symbols should be consistent across all ports.

not a compiler bug. Once a new release of KAME with a proper fix

GCC 4.1 gets many uninitialised variable warnings wrong. We should
|
|
|
|
|
really audit all the old hacks like this when older compilers are
|
|
|
|
|
removed from the tree, as many are probably no longer required.
|
2006-05-15 08:55:13 +04:00

The problem is that it does not recognize initialization via function
|
|
|
|
|
call pointer. I.e.
|
|
|
|
|
int p;
|
|
|
|
|
foo(&p);
|
|
|
|
|
does not mark p as initialized.
