I've added to the vault an enhanced versionof the Boost compiler_status.cpp file. It is named compiler_status2.cpp. The original version creates a table showing one row for each test and one column for each compiler. When there are several results for each compiler such as debug, release, different variants, etc, the only the "first" set of results is displayed. This version displays ALL results for each compiler. The included example shows part of the testing done for the serialization library. In all other respects it is identical to the orginal program.
