We tend to have #ifdef statements around (known) platform dependent
pieces. Rcpp::Timer is a relatively new one.
Regarding Cygwin, the "official" position in R circles is that it is not
supported. Because R does not come 'as a Cygwin build' from CRAN, not too
many people use it. That said, we do try to help provided ...

... you can help yourself. I would suspect that you can work out a proper
solution using the standard combination of compiler and os defines. If so,
please send us a patch. If the patch does not break anything, we'd be happy
to carry it forward.
Concretely, src/timer.cpp is a pretty short file which starts with
#if defined(_WIN32)
#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#elif defined(__APPLE__)
#include <mach/mach_time.h>
#elif defined(linux) || defined(__linux) || defined(__FreeBSD__) ||
defined(__NetBSD__) || defined(__OpenBSD__) || defined(__GLIBC__) ||
defined(__GNU__)
#include <time.h>
#elif defined(sun) || defined(__sun) || defined(_AIX)
#include <sys/time.h>
#else /* Unsupported OS */
#error "Rcpp::Timer not supported by your OS."
#endif
which shows that your error message
| g++ -I/usr/lib/R/include -DNDEBUG -I../inst/include/ -ggdb -O2
| -pipe -fdebug-prefix-map=/pub/devel/R/R-3.0.1-1/build=/usr/src/debug/R-3.0.1-1
| -fdebug-prefix-map=/pub/devel/R/R-3.0.1-1/src/R-3.0.1=/usr/src/debug/R-3.0.1-1
| -c Timer.cpp -o Timer.o
| Timer.cpp:35:6: error: #error "Rcpp::Timer not supported by your OS."

worked as intended -- nobody had yet worked out a supported setting, so by
default we stop.
Hope this helps, Dirk
