Problem with '-flto=N' on MinGW

[niXman]

HI,

I've built MInGW using the sources GCC version 4.7.1.
When using LTO '-flto=N' when N greater  1 - I get the following error:
> "make": [C:\Users\niXman\AppData\Local\Temp\ccl7QYlh.ltrans0.ltrans.o] Error 1 (ignored)

If I use '-flto' или '-flto=1' then the error is absent.
Tell me please, where is this error printed from? Because of what?
This error is found also in gcc-4.6.3 and gcc-4.7.0.

I'd like to have an working LTO whith more than one thread.

Thanks!
