Package: libc6-dev
Version: 2.3.2.ds1-10
Severity: normal


The following trivial program gives a compile warning using gcc-2.95 or
gcc272 on my debian testing system. gcc-3.2 and gcc-3.3 are both fine.

#include <signal.h>

int main (void)
{
    return 0;
}

The warning I get is:

In file included from /usr/include/asm/sigcontext.h:4,
                 from /usr/include/bits/sigcontext.h:28,
                 from /usr/include/signal.h:326,
                 from foobar.c:1:
/usr/include/linux/compiler.h:17: warning: `__attribute_used__' redefined
/usr/include/sys/cdefs.h:195: warning: this is the location of the previous definition

I'm not sure if I should blame libc6-dev or linux-kernel-headers for this one.

Some additional system information not collected by reportbug:
gcc272 version 2.7.2.3-18
gcc-2.95 version 1:2.95.4-19

Hope this helps,

I tested with the latest sid environment:
	
	gotom@moog:~/debian/glibc/bugs/222055> gcc-2.95 -Wall test.c
	gotom@moog:~/debian/glibc/bugs/222055> gcc272 -Wall test.c

No problem.

I tested with:

ii  gcc272         2.7.2.3-18     The GNU C compiler.
ii  gcc-2.95       2.95.4-22      The GNU C compiler
ii  linux-kernel-h 2.5.999-test7- Linux Kernel Headers for development
ii  libc6-dev      2.3.2.ds1-13   GNU C Library: Development Libraries and Hea

I close this bug.  If you still have problem, please let me know and
reopen this bug.
