Actually,

g++-3.0 -c -Wall -pedantic -g rand.cc

gives an error, not a warning.

In file included from rand.cc:4:
/usr/include/Rmath.h:520: declaration of `double log1p(double)' throws
   different exceptions
/usr/include/bits/mathcalls.h:125: than previous declaration `double
   log1p(double) throw ()'
make: *** [rand.o] Error 1
