What compiler flags?  Do you by chance use -std=c++0x ? That has given us
fits as it fails under 'R CMD check' but not when the unit test files are
running one by one.

FWIW everything is fine here with 

  CFLAGS=-O3 -g0 -Wall -pipe -pedantic -std=gnu99
  CXXFLAGS= -g -O3 -Wall -pipe -pedantic -Wno-variadic-macros 
  CC=ccache gcc-4.5
  CXX=ccache g++-4.5

and a fresh install and check of Rcpp 0.9.4 on Ubuntu 10.10 amd64.
