[boost] [thread]link problem with ibboost_thread-vc71-mt-gd-1_38.lib

Hello, I had a dll using MFC as shared library which works fine with boost 1.35. Recently, I've started to look at 1.38 and got the following link problem: libboost_thread-vc71-mt-gd-1_38.lib(tss_pe.obj) : error LNK2005: __pRawDllMain already defined in mfcs71d.lib(dllmodul.obj) libboost_thread-vc71-mt-gd-1_38.lib(tss_pe.obj) : warning LNK4006: __pRawDllMain already defined in mfcs71d.lib(dllmodul.obj); second definition ignored I've searched on internet and mailing list archive and didn't find a solution to the problem. Does anyone have an idea? Thanks, Xuewen
