Iam not sure what you are refering here
But you can use the /MD or /MT switch with VC
alternatively check the runtime library options in C/C++ tab in project
settings in the VC IDE

Hi

There's this bug report (#420659) on libcurl over at
http://sourceforge.net/tracker/?func=detail
<http://sourceforge.net/tracker/?func=detail&atid=100976&aid=420659&grou

It looks as if the Windows name resolver could have some multi-thread
problems.

Does anyone know if there exists some multi-thread option to the
Microsoft
compiler that'll make things work better? Apparently, the Borland
compiler
has an option for it so I thought there might be one in MSVC too.

Other ideas regarding the cause of the problem are welcome too.
