Hi Cyril,

Thanks. I read that, and mentioned it, but my concern with -pthread in the
CFLAGS and LDFLAGS is that it is a non-standard compiler flag. I
understand we have a number of gcc-isms in our build - but do we want to
add more?

I'm also struggling to find any kind of prescribed documentation on this
beyond the short blurb in the gcc man page which describes what this
option does, but not when to use it. I'll need something concrete to
justify changes to testcase Makefiles to Shuah.

Unfortunately, all these options are functional for me, while some are not
for Shuah, so I'm currently having to rely on documentation which seems
pretty sparse.
