While this particular error probably should be fixed (it's as
trivial as including stdio.h into test in auto/types/sizeof) - in
general using C++ compiler to compile C code isn't going to
produce anything good. These are two different languages.

Just create source file with appropriate extension and include
nginx header files in an extern "C" block, then write C++ code.
See src/misc/ngx_cpp_test_module.cpp for an example (really simple
one though).
