I have been unable to build threads on cygwin using gcc or
gcc-nocygwin. One thing I am puzzled by is that the tar file I
downloaded does not have make files in tools/build/jam_src as
David says.
Things have changed since 18 Oct 2002, when I wrote that.
The instructions for rebuilding bjam are at:
http://www.boost.org/tools/build/jam_src/index.html#installing
If you're going to invoke it from within cygwin, you want the "Unix
type platform" instructions.

I looked at the website. The only mention of building bjam for 
gcc-nocygwin is with using build.bat. So, I ran (from a cygwin command
line) 

build.bat gcc-nocygwin

and, it failed while trying to build fileunix.o, as follows:

Is there some other way to build bjam for gcc-nocygwin? Or, should I
build bjam for cygwin, and, when I build boost use the gcc-nocygwin
toolset?

I don't know, but rebuilding bjam within cygwin is as easy as
make CC=gcc
from within the tools/build/jam_src directory.
Good.
John said it won't work for Win32 executables, but it seems that
it will
work for cygwin-based apps; I might find a use for that.
