Bug#485135: libc6-dev: XSI-compliant version of strerror_r() not useable from C++

[Sven Gaerner <sgaerner@gmx.net>]

Package: libc6-dev
Version: 2.7-10
Severity: normal


Hi,

I want to use the XSI-compliant version of strerror_r(). The code below compiles
without any error using the gcc.

Trying to compile this code as C++ code using the g++ always fails because the
compiler always tries to use the GNU version of strerror_r() that returns an
char* instead of an int. Trying to define _XOPEN_SOURCE=600 does not change
anything.

I used the sample code below:
#include <string.h>
#include <stdio.h>
#include <errno.h>

int main(int argc, char **argv) {

  char buf[1024] = "";

  int rc = strerror_r(EINVAL, buf, sizeof(buf)-sizeof(char));

  printf("%d %s\n", rc, buf);

  return 0;
}

Also using the C++ includes cstring, cstdio and cerrno does not change anything.

The following C++ compilers are installed:
ii  g++                           4:4.2.3-10 The GNU C++ compiler
ii  g++-4.1                       4.1.2-19   The GNU C++ compiler
ii  g++-4.2                       4.2.4-1    The GNU C++ compiler

And g++ is a link to g++-4.2.
