I downloaded and installed cctools-590.12, and that did indeed solve the
gcc-4.1.0 bootstrap problem.
However, today I discovered that the newer cctools break gcc-3.4.x.
A zero-sized global variable, e.g. "struct { } unused;", gets translated
into a ".comm _unused,1" by gcc-4, but gcc-3.4 generates ".comm _unused,0".
The latter worked with the old cctools, but the newer ones mistreat it
as an unresolved reference leading to linkage errors.
