maybe the solution is ugly, but it should work. the macros are
predefined by gcc. more ugly things are used in debian/rules2 to make
sure that the libstdc++ build for i486 uses the i486 header, although
the compiler is built for i386.
gcc-3.2 always used the i486 header. so maybe you are right, that the
same workaround needs to be applied to the 3.2 header.
debian/rules.d/binary-libstdcxx.mk:
: # construct an atomicity.h file suiteable for i386 and above.
