compilation failure on latest Alpine 3.19.0

RcppInt64 fails to install on the latest Alpine Linux 3.19.0:

../inst/include/rcppint64_bits/functions.h:48:58: error: 'int64_t' was not declared in this scope
   48 | inline Rcpp::NumericVector toInteger64(const std::vector<int64_t>& v) {
      |                                                          ^~~~~~~
../inst/include/rcppint64_bits/functions.h:23:1: note: 'int64_t' is defined in header '<cstdint>'; did you forget to '#include <cstdint>'?

Indeed, the following one-liner fixes the installation for me:

diff --git a/inst/include/rcppint64_bits/functions.h b/inst/include/rcppint64_bits/functions.h

Yes, thanks, will apply the change. These things can happen with newer compilers. Odd that the CRAN reports page is spotless as the Oxford setup tends to be 'early' and catch these things too.
