#2902: Assignment within condition expression warning

Milestone:  To Be Determined     |   Component:  spirit  
  Version:  Boost 1.38.0         |    Severity:  Cosmetic
 Keywords:                       |  
---------------------------------+------------------------------------------
 In many places in my own code I get the following warning from Microsoft
 compilers:

 <boost\spirit\home\qi\detail\string_parse.hpp> line 22 : warning C4706:
 assignment within conditional expression

 Of course on this occasion the assignment is safe and intended.
 However it is not a warning that we feel comfortable disabling globally.
 Hence it would be nice if the warning could be push'n'pop-ed inside Boost
 code to save client workarounds.

 An alernative - moving the assignment inside the loop - has the potential
 for a slight performance loss - an extra iterator deference.
