Do you always configure like that, or did something change since the
last time you bootstrapped?

I don't get these errors when linking make-docfile.exe, but I didn't
do a bootstrap.  (Not sure why it should matter, though.)

What does the following command display?

    gcc -print-file-name=libmingw32.a

I'm using

    gcc (GCC) 3.4.2 (mingw-special)

and won't touch gcc4 with a 3-mile stick, until 4.6.x gets mature
enough, and I can have my debugging together with -O2 again, like I
had with 2.7.x and 2.8.x.

But yes, you can use GCC 4, modulo the caveats in etc/PROBLEMS.
