bits/predefs.h missing in trusty package repo

[Shrikrishna]

predefs.h is one of the headers needed to compile against 32 bit binaries in a 64 bit system. It's usually present in libc6-dev-i386 package. (http://packages.ubuntu.com/search?suite=saucy&arch=amd64&mode=exactfilename&searchon=contents&keywords=predefs.h), but it isn't so in trusty. (http://packages.ubuntu.com/search?suite=trusty&arch=amd64&mode=exactfilename&searchon=contents&keywords=predefs.h). It's not present anywhere else either. So kindly see to it that it's added

Can someone please look into this? I'm not able to build a lot of projects because of this nag

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Meric Sentunali (msentunali)]

this affects me too, I can't build u-boot under yocto system due to this bug. it was working before upgrading to 14.04.

It's not "missing", it no longer exists in glibc 2.19. What problem is this actually causing? Reading the old bits/predefs.h, it throws this error:

# error "Never use <bits/predefs.h> directly; include <stdc-predef.h> instead."

The new stdc-predef.h now completely replaces it. So, given that you should never have been including it directly in the first place, I'm at a loss as to how anything's changed. :P

libc6-dev:
  Installed: 2.19-0ubuntu6.6

libc6-dev contains /usr/include/x86_64-linux-gnu/sys/types.h
types.h includes #include <bits/predefs.h> on line 323

When compiling things which contain #include <sys/types.h>, I get:
In file included from /usr/include/x86_64-linux-gnu/sys/types.h:25:0,
                 from scripts/basic/fixdep.c:106:
/usr/include/features.h:323:26: fatal error: bits/predefs.h: No such file or directory
 #include <bits/predefs.h>

There does seem to be some problem there.

Any updates on this?

Not sure what has changed, but it seems to work okay for me now.

GCC was updated from 4.8.2-19ubuntu1 to 4.8.4-2ubuntu1~14.04, which seems like the only relevant recent change.

I don't see anything relevant in the changelog though
