It's a minor misunderstanding. In response to some problems the OP was 
having in running msvc from a cygwin shell he responded with the bjam 
commands as run from the cygwin shell. But those commands never [1] run 
within the cygwin shell. The commands are written to a temporary BAT 
file, and CMD.EXE is popen executed to run the .BAT file. That behavior 
wont change. Hence any fixes that involve it running directly within the 
cygwin shell are irrelevant.

[1] I think it's possible, with some hacking, to force it behave 
differently.
