That's why something is very odd and someone should take a look at this.
That system isn't a pc with low ram, it's a production server with enough
ram and there isn't any swapping going on during compilation, although it
does grab nearly a whole processor for itself, so the system has to function
off the rest.
I have no troubles like this compiling other packages, this only happens
with gcc. I tried gcc 4.3.1 recently and there were a lot more errors and
the same thing happened.

There is a lot more ram than this and no swap space is getting used during
compilation, so this isn't it (I don't think so).

That's right.

Should I send the header file?
