complex is not currently reserved, but it is in the draft stanadrd
revision. (I might see the confusion. It does not say `to be passed to C',
and it means after passing to C.)

"complex"
No! Use complex in interpreted R code and Rcomplex in C.
We will shortly have compatibility headers for the C code that covers this.
Foreign.Rd has not yet been updated to reflect this change, but
the Writing R Extensions manual has.
