Actually we expect that _Bool will be used only via the typedef
"bool" in <stdbool.h>. The reason for the spelling was to use
an identifier that was within the namespace already reserved
for C implementors, so as not to impact any existing code.
Similarly for the complex type(s).
Note also that _Imaginary is not required by C99. There was
considerable debate about the utility (or not) of a purely
imaginary type, in the end deciding that there was insufficient
utility to require it.
There are reasons behind all of the C standards committee's
decisions. Often they reflect practical constraints such as
wanting not to conflict with existing strictly-conforming code.
If VS2005's wchar_t is truly not assignable then it doesn't
conform to the C standard.
