When I build and run config_info using msvc-stlport I get the output below which doesn't seem correct. I get no reference to stlport. When I investigate the bjam output I find (for another test) I find that the following is being used for the command line: "cl" /Zm800 -nologo /EHsc -c -D_STLP_DEBUG=1 -D_STLP_DEBUG_UNINITIALIZED=1 -D_STLP_USE_DYNAMIC_LIB=1 /Z7 /Od /Ob0 /EHsc /GR /MDd -I"C:\BoostMainCVS" -I"c:/Program Files/microsoft visual studio\vc98\include" -I"c:\STLport-4.5.3\stlport" -Fo"..\..\..\bin\boost\libs\config\test\no_ded_typename_fail.test\msvc-stlpo rt\debug\threading-multi\no_ded_typename_fail.obj" -Tp"..\..\..\libs\config\test\no_ded_typename_fail.cpp" This indicates that the Microsoft native include is specified BEFORE the STLPort one. This would explain why the config_info doesn't reflect the STLPort usage. Can someone tell me what I should be doing differently?
