workaround for building with express toolchain on windows
workaround for building with express toolchain on windows

intsafe.h and stdint.h both define INT8_MIN et al. with no guards,
and so can't both be included. Because dependencies do this deep
in their internals, avoid this problem by including intsafe.h,
and then #undef'ing the conflicts in precompile.h (which is included
in all .cc files). intsafe.h's include guard symbol stays defined
so that any subsequent inclusions do not cause problems.
