New Revision: 52168
URL: http://svn.boost.org/trac/boost/changeset/52168

Log:
Check if value of NO_COMPRESSION/NO_ZLIB is 0 or 1.

Originally, only presence of these variables was checked.
Unfortunately, iostreams documentation said, incorrectly, 
that NO_ZLIB and NO_BZIP2 default to 1 on Windows, which
caused some users to pass NO_ZLIB=0 explicitly, together 
with other variables,thereby still disabling zlib.

This match makes Jamfile forgiving of this error.

Fixes #1967.
