As direct as all this was, I have to say that I have experienced
*everything* he has, and more. The .bat file I have for building
boost is getting rather large with all the stuff I have it do just to
work-around so many things. I have mentioned a few of those on the
boost lists, multiple times actually, but nothing has come from it.
The build system definitely needs to be cleaned up a bit though, or at
least made more consistent. That Boost.Regex and ICU annoyances took
a bit of time to figure out when I first experienced each of those
errors, and the odd thing, those errors have been propagating through
many version now, and new ones seem to keep popping up, many of which
I have talked about on this list, how to fix it, why it should be
fixed, but no one that has commit privileges has yet done anything.
