Re: [Boost-build] bjam and -fPIC

Thanks for all of your comments.

The reason I asked about -fPIC showing up in the link steps because by
passing "linkflags=-fPIC" to bjam, I expected to see -fPIC in the link step
-- regardless of whether or not it's actually needed.  I don't believe it
has any effect on the link step, but that's besides the point.  I could have
passed "-abcdefg" and would still expect bjam to pass it along to ld.

Thanks,

Mike
