Package: libc6-dev
Version: 2.3.2.ds1-3
Severity: normal

When building with gcc-2.95, I get the following error message:

  bmc@stonewall:/tmp% gcc-2.95 foo.c
  In file included from /usr/include/asm/sigcontext.h:4,
                   from /usr/include/bits/sigcontext.h:28,
                   from /usr/include/signal.h:326,
                   from /usr/include/sys/wait.h:30,
                   from foo.c:2:
  /usr/include/linux/compiler.h:56: warning: `__attribute_used__'=20
  /usr/include/sys/cdefs.h:195: warning: this is the location of the=20
  previous definition

I have found that this occurs anytime one includes both unistd.h (which
includes, several files later, sys/cdefs.h) and sys/wait.h (which
includes linux/compiler.h). foo.c includes only these two headers and
returns 0.

This redefinition, which is ignored in newer gccs, is problematic in
2.95 because it causes building with -Werror to fail. The alternative is
special-casing code which uses both these headers, which is ugly and

I do not remember having this problem with 2.95 before my upgrade to
experimental, but I am not sure. It seems to only have occured in the
past few days, when I rebuilt a particular file that I was working on
with gcc 2.95 as a test.
