[Boost-users] How to suppress vcvarsall.bat call?

Hello When compiling Boost 1.38.0 with this command, bjam 3.1.17 insists on calling vcvarsall.bat before executing the actual build commands. bjam -q -sNO_COMPRESSION=1 --build-type=complete --abbreviate-paths --toolset=msvc-8.0 architecture=x86 address-model=32 However my environment already includes all necessary settings to execute cl, link,... So I would like to skip the call to vcvarsall.bat. Is this possible using a bjam command line argument? Regards, Peter.
