Problem compiling with clang on Windows

Testing with clang on arm64 on Windows we see:

** libs

Previous topics in RcppCore/Rcpp#1148 and RcppCore/Rcpp#897 suggest a likely issue is something is included that redefines TRUE, probably in your windows.h include: https://stackoverflow.com/a/5663743/318752
