Or he may override them from command line:

bjam -sTOOLS=mingw -sSUFLIB=.a -sSUFDLL=.dll -sSUFOBJ=.o

(Well, at least sSUFLIB and -sSUFDLL seems to work. I haven't tried -sSUFOBJ
yet, as I was only interested in having the built libraries named for easier
inclusion in my projects' makefiles.)

Care to enlighten a newbie as to why you call these file extensions
cygwin-protocol? I can't think of any libraries apart from Boost, whether
compiled using MSYS or plain MinGW, that don't use them. Then again, Boost is
the only one I've compiled using bjam. I thought these extensions where a
general convention for g++ irrespective of build environment.

Kind regards,
