Description:
libmysql.dll for windows has become much larger in size than ever.

In 5.0.37, it was 1,531,904 (2,035,712 with debug info).
In 5.0.41, it is  2,031,616 (2,617,344 with debug info).

Approximately, increasing by 30%.

I have no trouble about this, but I'm just reporting 
as I noticed it by chance. If this change is technically 
reasonable, it's OK. Otherwise, please address it.

How to repeat:
N/A

Suggested fix:
N/A

Thank you for the bug report. The explanation of sizes difference (debug
