sure, if we'd ever looked in there :-)

on this subject, there've now been three things (LFS, ELF_OSABI_LINUX
and setjmp) which people have said `oh yeah, thought we might have some
problems with those, someone mentioned that' (or similar) once the problem
was found.  would anyone care to remember anything else that they thought
`might be a problem at some point'?

I vaguely remember that.  Searching the list archive finds:
http://lists.parisc-linux.org/pipermail/parisc-linux/2000-July/009002.html

so it's dhd's fault :-)
