at least MSVC (could be others, too, this is a compiler specific jam-file
issue) fails to fully compile Boost.Context if there's any user specified
preprocessor define passed to B2 that has characters that command prompt may
interpter as control characters, e.g.
``define=BOOST_USER_CONFIG="<SuperiorConfig>"'' that is.

The problem lies in how tools\build\v2\tools\msvc.jam handles .ASM (and .RC
files, too, not that Boost yet uses any during the build) files:

line 314:
        actions compile.asm
            $(.ASM) -c -Zp4 -Cp -Cx -D$(DEFINES) $(ASMFLAGS) $(USER_ASMFLAGS) -Fo
"$(<:W)" "$(>:W)"

As command line is not passed thru a .RSP file (just a normal text file where
the rest of the command line arguments are read) unlike compile.asm's (and
.rc's) counterparts do, characters such as "<" and ">" affect the control
flow, which in this case is not what user wants (at least not what *I* want :D).

So, as a fix I propose that either do a full .RSP treatment or simply enclose
defines inside a double quotes ("-D$(DEFINES)"); That should fix it.

(Not sure if $(INCLUDES) should be passed to $(.ASM), in this particular
example it's the not the root cause anyway [<SuperiorConfig> not being found
due to missing include path] as no .ASM file currently actually includes any
[external] file.)
