First, while I say this affects netBSD current, I don't have a
build less than a few months old, so it is possible this has
already been changed there, though I doubt it.
/usr/bin/krb-config --cflags (on NetBSD 4* and NetBSD 5* and
NetBSD current at least of last April) generates
That causes programs that use it (or more often, have it foist
upon them) and which do
or #include "file"
to potentially find /usr/include/krb5/file instead of whatever
they were intending to find.
The only rational reason for ever doing -I of a sub-directory
of /usr/include is when some subsystem wants to override the
standard include files (for example, while I have no idea if
it ever needs to, or does, I could imagine threads possibly doing
that, with a different version of (perhaps) <resolv.h> for use
by threaded programs),
Aside from that, any program that wants to include something that
is installed in a subdir of /usr/include should simply
That's the way it has always been for sys/* net/* netinet/* arpa/*
and all the rest, and I cannot imagine why the krb5 directory needs
to be different. Certainly it doesn't include files that are
overriding standard files in /usr/include - rather they're just
polluting the namespace of programs that aren't expecting that
stuff to exist.
For an example of how this screwed things, see PR pkg/40198 (skip
past the early bug report, and go down to the more recent part
where this issue was the problem).
Run krb5-config --cflags and observe the output.
Change krb5-config so it omits nothing with the --cflags option
(the -I is currently the only output, and it is bogus).
Then fix anything (should there be anything) that has stupidly
depended upon this behaviour, to include <krb5/file> instead of
