v8/build/standalone.gypi
thakis 39bef217a3 Let v8 standalone builds use update.py instead of update.sh. 
update.sh is gone in chromium, and using update.py will do the right
thing both before and after the deletion in chromium (previously,
update.py used to call update.sh internally on non-win).

This also has the benefit of working on Windows.

No intended behavior change.

# C4091: 'typedef ': ignored on left of 'X' when no variable is

# This happens in a number of Windows headers. Dumb.
4091,
# C4127: conditional expression is constant
# This warning can in theory catch dead code and other problems, but
# triggers in far too many desirable cases where the conditional
# expression is either set by macros or corresponds some legitimate
# compile-time constant expression (due to constant template args,
# conditionals comparing the sizes of different types, etc.). Some of
# these can be worked around, but it's not worth it.
4127,
# C4351: new behavior: elements of array 'array' will be default
# initialized
# This is a silly "warning" that basically just alerts you that the
# compiler is going to actually follow the language spec like it's
# supposed to, instead of not following it like old buggy versions
# did. There's absolutely no reason to turn this on.
4351,
# C4355: 'this': used in base member initializer list
# It's commonly useful to pass |this| to objects in a class'
# initializer list. While this warning can catch real bugs, most of
# the time the constructors in question don't attempt to call methods
# on the passed-in pointer (until later), and annotating every legit
# usage of this is simply more hassle than the warning is worth.
4355,
# C4503: 'identifier': decorated name length exceeded, name was
# truncated
# This only means that some long error messages might have truncated
# identifiers in the presence of lots of templates. It has no effect
# on program correctness and there's no real reason to waste time
# trying to prevent it.
4503,
# Warning C4589 says: "Constructor of abstract class ignores
# initializer for virtual base class." Disable this warning because it
# is flaky in VS 2015 RTM. It triggers on compiler generated
# copy-constructors in some cases.
4589,
# C4611: interaction between 'function' and C++ object destruction is
# non-portable
# This warning is unavoidable when using e.g. setjmp/longjmp. MSDN
# suggests using exceptions instead of setjmp/longjmp for C++, but
# Chromium code compiles without exception support. We therefore have
# to use setjmp/longjmp for e.g. JPEG decode error handling, which
# means we have to turn off this warning (and be careful about how
# object destruction happens in such cases).
4611,
# TODO(jochen): These warnings are level 4. They will be slowly
# removed as code is fixed.
