Fixed bug 4662 - SDL failed to build due to error LNK2019: unresolved…

… external symbol _memset referenced in function _IMA_ADPCM_Decode with MSVC on Windows LinGao We build SDL with Visual studio 2017 compiler on Windows Server 2016, but it failed to build due to error LNK2019: unresolved external symbol _memset referenced in function _IMA_ADPCM_Decode on latest default branch. And we found that it can be first reproduced on ca7283111ad0 changeset. Could you please help have a look about this issue? Thanks in advance!
