OK, I've figured this (at least) problem out; the file being referenced
by <bits/atomicity.h> is:

  .../arm-linux-uclibc/include/bits/atomicity.h

Which has all the ARM-specific inline asm for the "exchange_and_add()"
et al. functions, but where the definitions of "_Atomic_word" etc. is
in the *other* <bits/atomicity.h> file, located in:

  .../arm-linux-uclibc/include/c++/arm-linux-uclibc/bits/atomicity.h

So, by making the *horrible* kludge of adding:

  #include "../c++/arm-linux-uclibc/bits/atomicity.h"

right after the "#include <inttypes.h>" line, Qt 3.3.2 builds under
uClibc 0.9.26 . (Qt takes next to forever to build, but I've gotten
so far at least libqte-mt.so).

... but my question is *why* did I have to do that? Did some file not
get grafted into another by mistake (it sure looks like those two files
needed to be merged or something). It seems as if any program that
used "stl_alloc.h" (i.e., quite a few of 'em) would have barfed and
someone else should have caught this by now. (I even rebuilt my toolchain
from whatever snapshot was available on Sunday afternoon PST).
