Discussion on Chap. 6 Glibc compile problem...

I've been doing more reading on the compilation error that occurs on some
AMD (and newer Intel CPUs) and also on my Crusoe processor during the make
check of glibc in chapter 6... and there's a good reference to it in the
Chapter 5 glibc section of 'da book':
Here is a list of the most common issues we are aware of:
* The math tests sometimes fail when running on systems where the CPU
is not a relatively new genuine Intel or authentic AMD. Certain
optimization settings are also known to be a factor here.

The Glibc in Chapter 6 is the one we'll ultimately end up using, so that is
the one we would really like to see pass the tests (but even there some
failures could still occur -- the math tests, for example). When
experiencing a failure, make a note of it, then continue by reissuing the
make check. The test suite should pick up where it left off and continue.
You can circumvent this stop-start sequence by issuing a make -k check. But
if you do that, be sure to log the output so that you can later peruse the
log file and examine the total number of failures.
So it sounds like if the glibc 'make check' fails only on the math section,
it's still a good compile & one can continue normally.
Is there a way for the profile to use 'make -k check' as noted above and
have nALFS 'track' how many errors there were in the testing phase (and/or
which test[s] failed) ?
Or, as my father-in-law used to say "am I just full of condensed milk?" ;-)

 as I was typing this, I was re-running the make check, and the
linuxthreads test also failed... hmmm... maybe it's not a good compile
after all... :-(
