So now we have 2 option:
1). Find a ways to get the current function on different platforms in
have some information for this way. （lot of #if defined ）
2). Just remove __FUNCTION__ from the code. Total 5 __FUNCTION__ in
source code when grep the code.
Personally, I prefer option 2 than option 1， any comments?
