Small additional note: One can determine the size and alignment *without* always resorting to trial execution. Autoconf does this by an ingenious "evaluation by compilation" technique in case of cross-compilation, see the implementation of AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
[...] 6. Test what the typedefs found are actually aliased to using C++ (there is no other portable way to do this). (Trial execution)
To be honest, I don't understand that point... Cheers, S.
