GCC in the Windows distribution of GHC

[cschmidt at deds.nl]

The Windows distribution of GHC includes GCC. Some header files
(such as iostream, algorithm, and so forth), however, are missing
(at least I was not able to find them).

I could, of course, download the correct version of GCC (this must be
version 3.2.3 for GHC 6.4), and put the header files where GCC
can find them. I only wonder if this is the right thing to do.

Were the header files omitted just to make the distribution smaller,
or for some other reason?

Cheers,
