Seems reasonable enough--and cleaner too.   The define command could accept 
both normal arguments and keyword args as well such as
  def define(*args, **kwargs):

Perhaps you could have:
    define('SIMPLEDEF', 'DEF2', FOO='bar', OTHER=0x8, YETANOTHER='help')
to get
   -DSIMPLEDEF -DDEF2 -DFOO=bar -DOTHER=0x8 -DYETANOTHER=help

The above interface allows for either approach.
