I don't know the exact line number, but look at ld/ldfile.c. Near the 
top it has the following definition:

[...]
#ifdef VMS
static char *slash = "";
#else
#if defined (_WIN32) && !defined (__CYGWIN32__)
static char *slash = "\\";
#else
static char *slash = "/";
#endif
#endif
[...]

and then four times calls concat() (concat.c from libiberty), e.g. like 
this:

[...]
if (entry->flags.maybe_archive && !entry->flags.full_name_provided)
     string = concat (search->name, slash, lib, entry->filename,
                      arch, suffix, (const char *) NULL);
else
     string = concat (search->name, slash, entry->filename,
                      (const char *) 0);

if (ldfile_try_open_bfd (string, entry))
[...]

But does it really matter? The definition of slash appears to be 30+ 
years old, and the binutils tools have been working successfully on 
Windows for many years. The issue clearly lies with the test cases.
