I might try that, but I guess I need to rebuild the tools to use 1.7.
I have now used gcc 3.4.3. and 4.1. with exactly the same cygwin1.dll.
They both could compile without showing these errors. So I guess 
cygwin is not at fault.

Why do you say competing tools? There's only 1 cygwin1.dll in the path.
And the other cygwin tools are not needed. gcc, as, ld etc are all in the
same directory, built with the same environment.

Yes, it's a linux file server with samba shares, underlying FS probably ext3.
I have not tried NFS as we mostly use windows and we have customer
reports with the same problem that only use windows (no linux server).

>4. Are you sure there aren't network issues here?

Do you mean IP-address conflicts? Or what else? As the windows network
doesn't show problems the basic setup seems fine.

Thanks for the help, I'll start looking into gcc changes.
