It's far more likely to be user error rather than a problem with your
GCC build (although I have to wonder why you passed so many redundant
options to the GCC configure script, including specifying
--with-arch_32 at the same time as --disable-multilib).

In  that case one possibility is that you haven't closed a namespace
properly. e.g. if you #include <signal.h> inside a namespace block,
then #include <sys/wait.h> outside the block, it won't be able to find
siginfo_t, because it was declared as something like foo::siginfo_t.

Trying to debug your code from incomplete snippets is impossible.
Please reduce your code to the smallest example that reproduces the
problem, and then show us that.  If you can't reproduce the problem
with a reduced example, examine what's different between it and your
real code.
