for 6.2 ?

the patch is for 7.0 (it includes tap and CMakeLists.txt) but could be back ported -- i'm too busy on assigned tasks at the moment

sorry, no braces around the for and if statmenets:

      Bug #47426: Parser.cpp won't parse "x=c:\windows"
        . now finds first of ':' or '=' for the split

hi jon, [at least i guess i'm talking to you :) ]
i don't know if this needs documenting, but pushing your way anyway.

ta, jack.

Documented bugfix in the NDB-7.0.8 changelog as follows:

        The NDB kernel's parser (ndb/src/common/util/Parser.cpp) did not
        interpret the backslash ("\") character correctly.

Closed.

Pushed into 5.1.37-ndb-7.0.9 (revid:jonas@mysql.com-20090930075942-1q6asjcp0gaeynmj) (version source revid:jack@sun.com-20090923021325-g0iixq1ssbl32my4) (merge vers: 5.1.37-ndb-7.0.8) (pib:11)
