Patch to fix linker (ld.exe) path limit of 260 characters for windows

In Windows OS for ld.exe getting error message " no such file or directory", if
the object file whose full path length exceed 260 characters.

Command:
ld.exe
C:\msys64\home\Jaydeep\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepah\increasepath\increasepath\increasepath\increasepath\test.o

Error:
ld.exe: cannot find
C:\msys64\home\Jaydeep\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepat
h\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\increasepath\test.o:
No such file or directory

To solve this problem, As per Microsoft suggestion to prefix "\\?\" to filename
(object-file) to make it work and it is working for absolute Path .

Please find the attached patch (ld.patch) which fixes this issue.

Also let me know if there is any other alternate way to handle this.
