OK. Guess I should go into some details. In order to perform any build 
action, the build system loads appropriate toolset file (is it msvc in your 
case?). It then uses "flags" rule to create a variables based on required 
properties, which variables are used in build actions. 

Precisely, you have <linkflags>x
msvs-tools.jam has
flags LINKFLAGS <linkflags> ;
which cause all values of <linkflags> properties to be added the the variable
LINKFLAGS. Then, rule called
vc-Link uses that variable. 

Now, how is it all related to your question. I think that order ot options 
will be retained in any case. If you look at vc-Link rule you'll notice that 
it uses LINKFLAGS not in the end of command line. Don't know why, actually -- 
I actually have no idea about options order even for gcc :-)

You can try moving LINKFLAGS to the end of command line in vc-Link and see if 
this works. Otherwise,
a new variable would have to be introduced, similar to LINKFLAGS.
