+ enabled o:var += <cString> optimization when -ko switch is used
I added this optimization few years ago but I haven't enabled it
so far.
+ harbour/tests/speedstr.prg
+ added test code for <exp> += <cString> optimization
Try this code compiled with -kc switch (disabled += optimization)
without any -k? switches (default, += optimized for all expressions
except <obj>:<msg>) and finally with -ko switch (+= optimized for
all expressions)
(Warning for larger string non optimized code begins to be _very_
slow, i.e. for '#define N_LOOP 1000000' it needs fee minutes to
pass single test)
