Hi,

After updating to Cygwin 1.7.8-1, I am seeing an unresolved reference to __=
xpg_strerror_r=20

This test program links successfully if I define _GNU_SOURCE to so select t=
he alternate strerror_r entrypoint.

Compile with "gcc test.c":

#include <errno.h>
#include <string.h>

int main()
{
    char err_buf[256];
    strerror_r(errno, err_buf, sizeof(err_buf));
}

It appears the leading double underscore has been added to the symbol twice=
, I see an ____xpg_strerror_r in libcygwin.a.=20=20

$ nm /lib/libcygwin.a | grep __xpg_strerror_r
00000000 I __imp____xpg_strerror_r
00000000 T ___xpg_strerror_r
         U __imp____xpg_strerror_r

Regards,
Greg.
