Try pasting it into a batch file instead.  That's
how Boost.Build actually runs the command.  Also,
try adding -d1 -d+4 to the b2 command line and see
if that shows anything interesting.

Given the error stopping just before the space of <<C:\Program Files>>,
couldn't it be be a quoting issue somewhere, rather than a truncation? --DD

'C:\Program' is not recognized as an internal or external command, operable program or batch file.
