[boost] [parameter] 'develop' branch breaks tests with VC++

Subject: [boost] [parameter] 'develop' branch breaks tests with VC++

In testing out potential changes in Boost PP against other Boost 
libraries, to make sure those changes break no code, I noticed that 
running tests in the Boost parameter 'develop' branch against VC++ ( 
msvc-12.0 ) creates a number of compiler errors related to Boost PP. 
These errors in my tests look odd and I cannot figure out from what 
source they are happening:

...failed compile-c-c++

If I test against the 'master' branch of parameter these errors do not 
occur. If I run the tests using gcc these errors do not occur. I believe 
changes that were made to the 'develop' branch of parameter are causing 
these errors.

Furthermore I do not see these errors in the 'develop'regression tests 
for parameter, so i am puzzled. Any help would be appreciated.
