#2290: Patch for GCC-4.0.1 compatibility (and better compile time).
--------------------------+-------------------------------------------------
 Reporter:  dave          |       Owner:  ramey        
     Type:  Patches       |      Status:  new          
Milestone:  Boost 1.37.0  |   Component:  serialization
  Version:  Boost 1.35.0  |    Severity:  Problem      
 Keywords:  workaround    |  
--------------------------+-------------------------------------------------
 This patch makes the tests build on GCC-4.0.1 and leaves out what
 I believe to be the unnecessary step of checking whether a metafunction
 class is actually a placeholder expression.  If I'm understanding
 correcetly,
 it will always be a metafunction class, and not just in the tested
 examples.

 Note that this patch is against 1.35.x; I know things have been shuffled
 for
 1.36 but I assume the same transformation can be applied elsewhere.
