Makes sense - That's the way the other examples are installed. Then I can
remove those branches when I am satisfied.

I'll look under 'rtems-4.6.2/c/crc/tests' and build them separately,
elsewhere.

I have already installed RTEMS and am gradually learning what I need to
keep. This will later influence the way we set up our code management.

Sorry, please excuse me.

Specifically, I have not been able to build 'tmtests/tm27' for the following
BSPs: mvme2307, mcp750, and mtx603e. The problem seems to be the IRQ macros
in their respective 'bsp.h's (which are all the same file:
'rtems-4.6.2/c/src/lib/libbsp/powerpc/shared/include/bsp.h').

You previously advised me to check for CVS updates - I did look, but not
successfully:

 1) At this location I am blocked by the corporate firewall except for the
'generic' http and ftp ports, and
 2) When I checked for changed files, I didn't see an updated 'bsp.h' in
connection with these BSPs, but I may well have missed it.

I'll recheck from a site where I can freely access the RTEMS CVS server.

Perspective:
My current interest in those BSPs is only to know whether my installation is
usable: I don't expect to run them. I will be using 'psim' until we select a
specific target.

Therefore I am quite happy to have what appears a successful installation.

Thanks again.

Regards.
