#2111: boost headers always include too many platform headers
-------------------------+--------------------------------------------------
 Reporter:  Alessio      |        Type:  Bugs        
   Status:  new          |   Milestone:  Boost 1.36.0
Component:  None         |     Version:  Boost 1.35.0
 Severity:  Showstopper  |    Keywords:              
-------------------------+--------------------------------------------------
 #including boost/config.hpp on MSVC causes the inclusion of a large number
 of platform header files (see below for a boost 1.32 example for
 shared_ptr.hpp). This *seriously* degrades compilation times. For large
 systems with >1MLOC the degradation is just impratical and puts off big
 projects from using boost completely.

 boost/config.h should be split into smaller function-specific header files
 (e.g. strings, streams, threads, etc.) and every boost header file should
 include only the functions it needs.
