             Bug #: 54444
           Summary: 32-bit glibc development headers required on GNU/Linux
                    x86_64, but not checked during configure
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: gerald@pfeifer.com


In the last week I twice ran into a variation of the following on two
different systems (operating systems):

In file included from /usr/include/features.h:382:0,
                 from /usr/include/stdio.h:28,
                 from /home/gp/svn/gcc-HEAD/libgcc/../gcc/tsystem.h:88,
                 from /home/gp/svn/gcc-HEAD/libgcc/libgcc2.c:29:
/usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or
directory
 # include <gnu/stubs-32.h>
                           ^
compilation terminated.
gmake[5]: *** [_muldi3.o] Error 1
gmake[5]: Leaving directory
`/tmp/OBJ-0901-0046/x86_64-unknown-linux-gnu/32/libgcc'

The fix is simple -- install 32-bit glibc development headers.  On openSUSE
this is in the glibc-devel-32bit package, and there are similar packages on
other distributions.

Instead of failing during the build, can we test this at configure time?
