#9879: compiler_status fails to compile in C++98 mode
----------------------------+--------------------------
 Reporter:  Arfrever.FTA@…  |       Type:  Bugs
   Status:  new             |  Milestone:  Boost 1.56.0

 Severity:  Regression      |   Keywords:
----------------------------+--------------------------
 compiler_status fails to compile in C++98 mode (which is default in GCC).
 This problem is a regression introduced in Boost 1.55.0. This problem is
 absent in older versions of Boost (e.g. 1.54.0).
 I use GCC 4.8.2.
