- <AliciaC> in recent glibc commits (tschwinge/Roger_Whittaker branch) there
- are references to _hurd_atfork_* symbols in sysdeps/mach/hurd/fork.c, and
- some _hurd_fork_* symbols, some of the _hurd_fork_* symbols seem to be
- defined in Hurd's boot/frankemul.ld (mostly guessing by their names being
- mentioned, I don't know linker script syntax), but those _hurd_atfork_*
- symbols don't seem to be defined there, are they supposed to be defined
- elsewhere or is th
- <AliciaC> does anyone know where the _hurd_atfork_* group of symbols
- referenced in glibc are defined (if anywhere)?
- <youpi> AliciaC: it's the DEFINE_HOOK (_hurd_atfork_prepare_hook, (void));
- in glibc/sysdeps/mach/hurd/fork.c
- <AliciaC> hm, is that not just a declaration?
- <youpi> no, it's a definition, as its name suggests :
- <AliciaC> (despite the macro name)
- <youpi> :)
- <AliciaC> ok
- <AliciaC> I should look into it more, I could have sworn I was getting
- undefined references, but maybe the symbol names used are different from
- those defined, but that'd be odd as well, in the same file and all
- <AliciaC> I mean, I do get undefined references, but question is if it's to
- things that should have been defined or not
- <youpi> what undefined references do you gaT?
- <youpi> s/gaT/get
- <AliciaC> I'll get back to you once I have that system up again
- <AliciaC> youpi: sysdeps/mach/hurd/fork.c:70: undefined reference to

- <AliciaC> fork.c:70: 'RUN_HOOK (_hurd_atfork_prepare_hook, ());'
- <AliciaC> DEFINE_HOOK (_hurd_atfork_prepare_hook, (void)); is higher up in
