There isn't: you have to edit msvccompiler.py (.compile_options) or use
a hack like the following:

#
# mx MSVC Compiler extension
#
# We want some extra options for the MSVCCompiler, so we add them
# here. This is an awful hack, but there seems to be no other way to
# subclass a standard distutils C compiler class...

from distutils.msvccompiler import MSVCCompiler

# remember old __init__
old_MSVCCompiler__init__ = MSVCCompiler.__init__

def mx_msvccompiler__init__(self, *args, **kws):

     apply(old_MSVCCompiler__init__, (self,) + args, kws)
     self.compile_options.extend(['/O2','/Gf','/GB','/GD', '/Ob2'])

# "Install" new __init__
MSVCCompiler.__init__ = mx_msvccompiler__init__
