thank you very much to spend time resources for it.
and next, I should be careful to send patch. so do not wast other
members' time resources for my careless mistakes.
the details are:
a. if modify code, need always compile again, at least.
b. reduce reply times, so can reduce some of my waste information.
I will let additional machine (a PC) for test and compile instead of
my current work machine, so when I have to do another things (normally,
it is), the individual machine can continue compiling or testing.
thanks again.
