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.

You can shorten this by excluding "/including.*$".
