There is no support for this (rev. B) board in eCos AnonCVS. There is
olpce2294 target in eCos repository which is another kind of hardware.
For example, the first LPC-E2294 H/W revision had differ NIC (CS8900)
and rev. B has DM9000 chip, and etc.

Where above command line (a way to build) came from?

You should use a way to build eCos test as that is described in eCos
documentation http://ecos.sourceware.org/docs.html If you use CLI, that
would be

  % export TARGET=olpce2294
  % ecosconfig new $TARGET net
  % ecosconfig add httpd
  % ecosconfig tree
  % make
  % make -C net/httpd/current tests

Then you have to find `httpd1` eCos test (monitor included) under
`install/tests/net/httpd/current/tests' directory.

Of course,  it will not work on rev. B hardware, but eCos AnonCVS
sources and eCos tools is not issue. (I checked that just now).
