どの特定のツールwafが「cxx_compiler」などとして選択したかをどのように判断できますか？模範的な無償：

def configure(ctx):
   print('Running ' + ctx.cmd + ' in ' + ctx.path.abspath() )
   ctx.load('compiler_c')
   ctx.load('compiler_cxx')

def build(ctx):
   print('Running ' + ctx.cmd + ' in ' + ctx.path.abspath() )
   # Here print which C++ compiler was chosen
   print 'Building cpp files with %s' % WHAT_GOES_HERE

def options(opt):
    opt.load('compiler_c')
    opt.load('compiler_cxx')

def configure(cfg):
    cfg.load('compiler_c')
    cfg.load('compiler_cxx')

def build(bld):
    print "Compiler is CC_NAME  %s  CC  %s"%(bld.env.CC_NAME,bld.env.CC)
    print "Compiler is CXX_NAME %s  CXX %s"%(bld.env.CXX_NAME,bld.env.CXX)
